as most of you know I was having the same issues that WOW had with the misfires and such. I to went to Z Fever today and from what I saw I had the same issues with the injectors not being scaled, stock timing and the such. after about 4 hours we had the car running right. ended up making 431 at 6psi. the car runs great now and feel much better about getting on the gas. They were also able to dignose the limp mode problem I was having. it seems that the air intakes were put on wrong. they were placed in front of the radiator instead of being off under the drivers headlight causing a ram air effect. this excess air was causing the computer to go wild because it was getting air when it didnt need it thus placing the car in a safe mode. I just flipped it around and hope this fixes the issue. I will report back on that but from just using a piece of cardboard and a high flow fan we could tell a difference in the air fuel. All in all I am very pleased with all the guys at Z fever. attached is a video they shot while I was there not the clearest but still fun to watch all the same.
