can anyone help me with tuning my 94 z28. i installed a paxton novi gss supercharger and the guy i paid to tune it is playing games, saying its mechanical and its not the tune. i had a tuning shop look at the tune and they said that its bad and needs a retune, i dont have enough for a shop to tune the car and the guy doesn't want to tune it right. i went over everything and nothings wrong with the engine and car. stock injector's and tune works fine. but his tune 60lb injector's and the supercharger it pops and bangs at idle. any help would be grate
