ok i have a small hesitation from stop to go when the car is warm...i have done air/fuel/pcv fitlers...plugs, cleaned iac, new coil, the rpms are good dont flucuate no miss or anything...engine sounds normal, anyways has anyone ever tried one of those plug in throttle response things from jegs/summit? you plug it in from your tps to the other harness and its supposed to give you better throttle response?? some one has to have tried it??

 

out of the hundreds of thousands of F-bodies out there no one ever bought one??

 

In general, the TPS "tricker" isn't going to do much an a 4th Gen LT1, because of the way the PCM reads the TPS sensor. If you have a problem with throttle response, its better to try and find the real cause of the problem, rather than trying to mask it with a band-aid. Not trying to be nasty.... just trying to explain the importance of solving the problem. There are other things that can cause the problem, like a leaking EGR valve, faulty coolant tempo sensor, faulty TPS sensor, vacuum leaks, failing OptiSpark, etc.

Have you had it scanned?
