TRX Fanatic
I just got done reading the Dusterhoff chronicles and how safe and good flex fuel is, which sparked me to post.
I plan on upgrading my 2022 TRX. Only minor mods I currently have are SLP resonators, AFE CAI, and a JLT catch can. I’ve been doing a lot of research and for remote tuning no one gets better reviews than Dusterhoff. I was leaning towards his 937 flex fuel setup. I love the idea of not switching any hardware or having to download in a different tune. My truck is located in the east valley of AZ and would run on E54 pretty much year around. Other than when I take a road trip to Southern California or Las Vegas, etc. I started reaching out to local shops about flex tuning. Here’s what I found: The two most well respected Mopar shops from my research in the Phx area are SRT autoworks and Cordes Performance Racing. The 3rd shop I spoke with was Niche MOTORSPORTS who installed IGLA for me. Here’s what they had to say.
SRT Autoworks: I’ve read they use Barth for tuning and he has a great reputation. They do NOT offer flex tuning. I spoke to Tommy and he said he doesn’t trust flex fuel tuning. This was a FB messenger conversation so I don’t have anymore information. If I use SRT autoworks I would be doing their “exotic killer “ package (upper, lower, t-stat, injectors, BAP, tuning, etc.). and have to swap pulleys and load the correct tune to switch between ethanol and 91. Anyone know if they use ID1050 or 1300’s for this package?
Cordes: I had an in depth conversation with Joe. They use NicD for tuning and he has a great reputation (actually tuned my 01 Camaro awhile back) A couple small things he said: He definitely recommends upgrading spark plugs (NGK2309) at the time of performance upgrades. He also said the stock cats will eventually fail at the levels I was looking at-which again is basically the same package as SRT autoworks. I would guess close to 1000 hp at the crank. FYI-SRT autoworks also does a “mid pipe” upgrade on their package so I’m assuming that deletes the cats? As far as flex fuel-Joe @ Cordes says they do not do flex fueling either and he does not recommend it. He basically said it works good until you get a bad batch of ethanol that has too much water in it, etc. and it cause a problem with the operating system regarding tuning. I asked if they would be willing to install Dusterhoff’s package and he said No. I actually get his reasoning-shop blaming the tuner and tuner blaming the installer if there is a problem.
I like the idea of using someone local and their tuner so there is no finger pointing and I have somewhere local to bring it if a problem arises. Lastly Niche Motorsports also does not do flex fueling. They said they use a tuner who owns “shophellcat.com”-I don’t remember the name they gave. I did not ask their opinion in general on flex fuel.
Anyhow, love to hear everybody’s input. I know AZdinopower has used DT937 and now DT997 setup (with some small differences) and hasn’t had any issues. And is there any shop in Phx that would actually install Dusterhoff if I went that route? I am not throwing any shade at any of these shops or tuners-I just want to be informed when I make a decision. Thanks!
