Ok so i'm sure i'm not the only one having bad luck in the Chicago land area finding a tuner. I have a rcsb 01 Sierra 6.0 with a 76 mm and meth. Im on motor # 3 trying to find a tuner that can get the job done. Does anyone know of a tuner in the area or for what its worth with in a few hundred miles that is very good and will actually call you back!!! Im not asking for much just some one who cares about there work. I could tell you who i have tried but i would rather not talk bad about anyone. Thanks boone
