Have a Paxton on my '96 GTS. Have several small uprgrades added on the system (bigger injectors(50), fuel rails, smaller pulley(275) 4R tuning. The car is making 670 RWHP and 725 Lbs of torque at 5000 RPM's w/ 10 lbs. of boost. Now the problem comes in. The car basically shuts down at 5000 rpm's. I am thinking it has to be the fuel system since it is stock. The injectors are at 82% and the air fuel ratio is 12.4 when it shuts down. Also the map sensor hits 5 volts at 4500 rpm's. I have gotten this close I hope I do not have to put on a new fuel system. If I do can anyone help there, if not what should I try. I am thinking this car should make 750 RWHP. Help please.
Fuel System?????
