does anyone have any dyno sheets with/without the jet chip, I have one but it was on the car when I bought it. eventually I will get rid of it and get a custom chip, but for now it will stay.
About the tuning I dont believe JET chips can be tuned. Even if they could I doubt you could find a tuner with the software. The best you could probably do is send the chip to Jet and have them tune to your modifications which isnt a true tune on a dyno.
