I getting my tune and Dyno done on Wednasday with the list of mods in my signature. This will be the first one ever and I honestly don't know how it all works. I know when im done I will know my HP, torque, air fuel mix, and all that stuff but how do they get it? Now my car is an auto... so do they put it in drive and mash the gas till they reach red line? Do i control the gas in the car? Do they? Do you do a run in 1st, 2nd, and then D? Do I shut O/D off?.........Anyone out there wana guess what my HP and Torque #s will be?
