Nice, the black car runs well. Needs to lose that God awful wing though.

What did the white car run?

And yes the TUNE makes the car. I don't understand some of these cars that have plenty of power yet the can't run right.

Who tuned it, and what do they do that most other tuners can't get right?

GPI did the trans tune, IDK but a bunch are getting with them to fix and or improve their trans tune.

big hammer

same thing with the 6.2 trucks.

I did the original engine tune via email, and Andy only picked up a few horsepower on the dyno over what I had in there.

Im not necessarily doing anything others aren't, its just that I don't settle for it being close. It has to be dead nuts on or I wont let it go.
