I have 1999 camaro ls1 383 stroker tgat has a fast 102 tb and intake cam and heads. I believe that when it was tuned the tb was not opening completely which means the tps would have been reading around 80 percent with the pedal to the floor if i were to fix this problem so the tb opens completely and the tps will read 100 percent would i need to retune the car?
