I tuned 10 vehicles today!! Ran into a problem with a 2002 Suburban. After reading the entire program sucessfully (according to the program) a message that an error had occured and that the PCM wasn't recognized. Needed a cal file ect...
Did I not or do I need to download additional Cal files?

OS#III Is the bomb... After tuning 4 vehicles guys were running home to get their Tahoes and Yukons, Pickups ect... Best part was I tuned a 4.3 V6 who raced a 5.3 untuned and beat him by a couple of feet. The 5.3 was stock.. LOL the guy with the 5.3 is going to ask his wife if he can get a tune :roll: so they can race again
