Guys,
My system is as follows: NXL kit, WOT switch, FPSS, Timing Tuner, 80 jets on a 02 Corvette. I tested the wiring and everything looked good, so I went ahead and made some test runs. The kit kicks in strong and pulls good but at the end of the run when I let off the throttle the car runs a second then dies. It starts right back up. I am using the Timing Tuner as a window switch(3200-5900) and to pull 6 degress of timing. I ahve not had the car on the dyno or had it tuned yet. Any ideas as to what might be happening?
Thanks
Chris

 

Chris,Whay are you pulling 6 degress of timing for a 80 shot?

 

Chris,Why are you pulling 6 degress of timing for a 80 shot?

 

I was told to use 2 degress per 50hp. So 4 degress for the nitrous, and 2 more degress for the additional hp from headers, Vararam, etc. Plus I thought it would be better to be safe than sorry.

 

Chris,I belive you are pulling out to much timing.
The rule of thumb is anything over a 150 pull out 2 degress for every 50.If you have not had any computer tuning where they advanced the timing put it back to stock.Not enough timing can hurt you just as bad as to much timing.
