Don?t hit rev limiter. - ZR-1 Net Registry Forums

Young1 · 07-21-2022

1990 car. 1991 engine with correct 1991 Haibeck chip. My project idles well and has great drivability. It won?t hit rev limiter in first and second gear. It flattens at 5,000, gets to 6,500 and stops. TPS is .58 at idle. FSM limit is .59. Fuel system pressures are Ok. Secondaries are working I can feel the kick at around 3,500. Vacuum system has been thoroughly checked and tested. Throttle blades visually open 100 percent and air cleaner is new. I have no codes on scanner and no check engine light. It is not making that strong pull of power to rev limiter. What other parameters should I check? Need help. I have a buyer for the car.
