Rear wheel drive tuning! But I need your help!!

I had a highly modified Chevy duramax diesel. First year it was in the shop 8 months out of the year. Next year wasn’t much better. Never again. I just want a 2wd option lol.
Yeah. I went down that rabbit hole too... and I’m not going to do it again either. You just drown in trying to keep it running and then the thing is broken when you need it or want it. When it works.... it’s the coolest thing going.... but when it doesn’t... it’s just huge stress.

for this TRX when it comes.... I’ll do bolt ons... retrax powertrax, rims and tires, maybe some stereo stuff... the tazer sounds fun if it doesn’t void warranty... I’d consider a proper level... some good high flow air filters perhaps... I’d consider a catback if one sounds dynamite like AWE or Corsa... I think it might sound super sexy in titanium too! But my days of bigger blowers, bigger power, 100 octane, etc.... behind me. Been there, done that. Over it.
 
I know, but if you have never been thru this nightmare, you just don't realize how badly your screwing yourself and what your getting into, until its too late.

Let face it, most of these tune shops don't have cash equity to pay you back for purchase and undo what they did to your truck and restore it to stock. Even if you waste 3 years and $100,000+ in attorney's fees, once you get that judgement, they just go bankrupt.

Reality is, you have no recourse, if you don't have stacks of cash to sick a high end lawyer on them. And even doing that, is throwing good money after bad money, you will never recover.

I would highly recommend waiting and seeing what new parts are designed for TRX upgrade, why anyone would want to be the test subject and suffer thru the growing pains. Plan your upgrade and then execute step by step, that way your only on step from not being in the twilight zone and no way back.

I don't know how these tunes are going to happen when you cant get a 2021 PCM and I don't believe anyone has cracked the 2021 PCM yet?

Sorry guys, just don't want anyone to get screwed over.
I was told they are crackable but you need to send in your unit as they cannot be purchased.

also, nobody smart spends 100k on attorneys fees for a 100k truck. You could probably wrap up a suit in 10k with a good lawyer. I bet you never even see a courtroom. Summary judgement ftw
 
Seems like a good idea and I'd be curious what the final results are. I personally don't want to do anything to void the warranty on this truck but it be cool if you guys found/made a 2WD eco-tune for just long high

I agree eco 2wd reduced power for long highway drive would be great
 
All I am saying is no one seems to take the approach of what if it goes bad?

The only reason I know is I have had to file 4 civil law suits in last 5.5 years to do with custom home construction and 1 to do with a viper.

They sell you on hope and dreams of having the king vehicle, but they never talk about if the project fails and they put as little in writing, documenting, what happen if x happens. Just because a shop has a good word of mouth or reviews means nothing, they just haven't had a major screw up yet. You need to make sure they are financially stable and can make something financially right, if something gets messed up. Most of these companies are just LLC's, filing their business taxes mashed into their personal 1040 return and they take every dime out of the company, to support their lifestyle. A company run like that, how are they going to return your $50,000.00 for engine modification they screw up and return your truck to stock? You are screwed period. Even if you win lawsuit or get arbitration judgement, they just go bankrupt.

Because state law statutes, state any company sued can not represent themselves in law suit, they need to retain counsel. Thus it becomes cheaper and more cost effective to just stall, delay, draft dodge requests...etc, especially if they don't have funds to defend the law suit or repay you back and fix damage. Most are in this position and its the default strategy attorneys use, stall it out until consumer quits. And it works. Most people cant take the stress and drama it puts on your entire life, and effect your entire family. They are counting on it. Its all part of the strategy.

Home builders and car tuners doing HP modifications are a lot a like. Usually the guy that owns the business was one of the best at what he did, working for another company and thought, why cant I make the big bucks. Where the problem comes in is these people are not trained or professional businessman, that know how to run a business, cash flow, have enough equity and risk and liability coverages for each specific project. In other words, they cut corners on the back end business side and when it goes bad, its really bad. They don't have the equity to cover mess ups, they are super nice when they are trying to sell you, but when it all falls off the rails, they just stop calling you back.

If you want to test a tuner, tell them whatever you want done, and you will sign a contract and pay in full when completed. Watch the ants balk at that and scurry back underground into the ant hive. A business that is not properly financially responsible/secure to cover the cost of the project upfront is a business you don't want to get involved in.

They want you to hand over your truck and whatever amount cash for project upfront. You take all the risk. In reality, if it goes wrong, they have basically no risk, because they know, most people don't have or want to waste the money to file a civil suit. And as long as they do one thing to the car and document it, then it sits there for 2 years, that is intent to start/complete the project. No criminal charges can be filled, its all civil. That is when it starts getting expensive for consumer.

Plus they are preying on your ego to increase your HP x amount, no one ever properly thinks out what if it goes bad and what are my recourses, if it does.

Summary judgement occurs only if contract is rock solidly clear and judge approves summary judgement. No a guarantee by a long shot. By the time it gets to this point alone, its gotten so ugly, both sides are dug in and are not giving an inch.

Summary judgement in a civil case, one party wants to move to a court decision without a trial. The other party will oppose, if they don't have funds, then just stall it out and run your attorney bills sky high. The judge reviews the facts (unless your attorney, re-writes the contract, everything is vague and disputable) of the case, along with any acceptable evidence provided by each party to support their argument and sees no point in having a trial. Then they force you into mediation, which fails more than half the time, then its onto discovery which takes almost a year, then depositions, then you have to start setting courts dates.

The other attorney can easily drag it out years, without almost any cost to defendant. The goal here is to wait out the consumer, until they just give up.

Just be careful.
 
Agreed that 2wd would be great.....strictly for burnouts and donuts...especially when it's time for tires. Fuel mileage.....ehhhh, I would have bought a Prius and put a Coexist and Bernie sticker on it if that mattered! 😉
 
2wd is dumb in a Hellcat, and even dumber in a Hellcat powered truck with no weight over the tires as it is.
True a 2 WD Hellcat powered truck is dumb some of the time, it is even more dumb to be in 4WD in cruise control going down the interstate in July getting 10 MPG. If a 2WD Hellcat is dumb all the time, explain all the 2WD Hellcat powered cars to me please?
 
Don't want to be a flame thrower but you all bought this truck with the knowledge that it is 4wd ALL of the time. There is always something that we find wrong with our current rides, but we also know there limitations.

I'm assuming there is a very good reason from an engineering standpoint that it is always 4wd. Your trying to chase maybe 1-2 mpg at best with a 2wd version but potentially sacrificing the integrity of the entire drive train also.

It's 100% no doubt safety.

Not many people that buy this truck understand what a truly fast 2wd truck feels like and the risk of the rear swinging out are incredibly high since there's no weight over rear axle.

I'm actually really grateful SRT did it this way so we don't have all the idiots sending this amazing machines to the scrap yards like they did with the Hellcat challengers and Chargers.
 
HP Tuners website shows the TRX being supported. You do need to send in your PCM (ECM) or a new PCM (ECM) to have it unlocked though. The part number is 68434939AA and looks like its on order restrictions. That said, same part number for the Jeep, Charger, and Challenger so if you can find one from those other models, should be able to get it unlocked and work in a TRX.
In regards to the force rwd mode in the tazer, I have read reports of the mode destroying transfer cases. The TRX has a different tcase, but just something to be aware of.

What’s your source of reports damaging the Tcase? Can you post them??

It was on a trackhawk forum and various fb pages. I didn't keep track of them, just stuff I saw while reading through. I'm not 100% sold on it being an issue considering how many have been sold vs reports of issues.

There are very few shops out that can modify a car or truck and do it right. I've built cars for years and it's pretty hard to bolt a bunch of crap on and slam the hood without having bugs to work out. I have a twin turbo duramax that makes 750 wheel and it's very reliable but I can't imagine the money it would of taken to have a custom shop do the work and do it right!!
 
The hellcat engine has been around for almost 6 years now. There are a handful of shops that work on them, and work on them well. Yes, the engine is in a new box, but still works the same. A good tune comes down to the person doing the tune. I'm sure we'll see pulley and tune upgrades soon. The trans tuning might take some time to sort out.

I have a feeling they made the internals of the TRX stronger than a normal hellcat motor. Also the factory tuning or injector more aggressive based on real world figures.

I haven't read a thing about that and if they did, they would've announced it. The hellcat is already beefed up compared to the 6.4. Tuning is tuning, a good tuner will be able to read the data and make changes based on that. If the injectors are already close to max duty cycle, they would tell you. The tune from the factory is more of a safe tune since it has to work reliably in a wide set of environments, you can usually get some efficiencies when the tune is tweaked to your specific vehicle. That said, would I jeopardize my powertrain warranty for a couple horsepower? No.
Also, completely opposite of everything the TRX is, I have seen some people get tunes to get better gas mileage (reduce throttle sensitivity, increase traction control, etc..)
