My last time to the track the car fell off around 2-3mph shortly after the opti started acting up could these two events be related? Has anyone else had the same problem. Thanks Josh

 

possibly, but only oen way to find out, hook up an Autotap to your car and scan the computer. check for misfire codes and see if there are any. however, weather and track conditions play a big role in car performance. you can go to the track on two back to back nights and the runs can vary 2-3 MPH. just check the car on autotap and see what the deal is with it.
