No more tuners wanting $400+ to tune your car... or a couple hundred if you make small changes.

I'm putting one on my 5.3 turbo setup.

Yes, I spoke with one vendor and he was pushing gm, Of course then he can tune it, I live in the middle of no where so if I was to take it to a tuner it would be minimun of 5 hr drive. thanks for the advice
