If you have the generic diablosport predator (7140), update the tuner to ver. 36. Plug it into your car, go to Options, go all the way down to OEM Select, and choose C&L. The unit will reboot itself and walahh, you now have a C&L tuner.Go to Performance Tunes and load the Racer Tune. Car should run like a top after that....good luck

CrazyAll, whenI bought the Racer vrs. Street I was aware there would be no difference or could be a little less preformance with the racer, but for future N/A mods it should be usefull. My objection was his problem was not the CAL but the tune.

I'm probably way off base, but since no one mentioned it, I will.
Do you have 93 octane fuel in your car?
Stupid question I know, but in my area the best we have is 91.
I was able to use the 93 tune, but had to reduce the spark by 2 degrees.
Ranmuch smoother after that.
