I dont know what to tell ya, Haro. It made a BIG difference in my car. It shifted at about 5300 on mine in normal mode at WOT. In performance mode it would not shift before the failsafe would kick in and kill the spark, Almost at REDLINE. Then again i had about $8,000+ of of new parts on the engine also. TRanny, Super Charger, Alt, AC compressor, water pump, Harmonic balancer, throttle position sensor, EGR, etc...
I dont know if that had a factor but the key to finding out what was done on this chip is to get whoever knows Dave Buckshaw to ask him what he done to it. Was it lilblazin?
