lol we get it your trying to convince yourself the DC package is worth it! Just get it nobody will be mad at you.I agree with you without a doubt but $2000 vs $2900 isn’t comparable. That’s nearly 50% more cost. So my point was, the kit OP posted isn’t far off from the other offerings available from outside tuners at the same cost.
A $700 difference when you are getting much much more is well worth it. Especially considering total cost will exceed 4K.
You are doing 99% of the work but only getting a 50% return compared with other kits.
