Ran my GSR at the strip. First run and it COMES on. Hasn't done that until I take it to the REAL drag strip for a test. Funny i was running mid 15s STOCK. Still running ok but engine runnin' kinda rough, a major difference from before. WHat tha hecks really wrong? timing, wires? already reset ECU millions of time.

 

Check to see what code you are putting out, that will tell us alittle more on what could be wrong.
