okay i got a SCT 4 bank memory chip i think. i know i have 4 tunes to choose from... #0 - 91 octane street tune; #1 - 93 octane race tune; #2 - 96 octane race tune (for the track on a 1:1 101/91 octane mix); #3 - Empty; #4 - stock tune; #5, 6, 7 - NO START :dunno: Jim, my tuner called this the "SWT 91 Octane, Ass Whoopin Chip/Tune" www.SWTuning.com i started out today with 209 rwhp / 286 rwtq and on the 91 street tune (i think) it went to 217 rwhp / 299 rwtq. i know its not much of a gain but my god it runs like he added 30 horses!!! i took it for a ride around the block, hit it coming out of the parking lot onto a straight and the tires broke lose real easy, slammed it into second and it got all kinds of silly. this is not common behaviour for this GT, bark second, yes... light'm up in second, NEVER!!! i did a second gear drift through a corner on a back road near the shop... had to feather the gas to keep it from coming around :dancing6: needless to say, IM FUCKIN THRILLED WITH THE WAY THE CAR IS RUNNING!!!
