560cc injectors, blow through z32 MAF, Isky cams, Jim Wolf springs, HX35 turbo, intercooler, Walbro 255 fuel pump, wideband O2 sensor, and Nistune.
So, what happens is that the car starts and idles fine. In neutral, there's no problem revving the engine. However, while driving, it bogs down and runs real lean when it gets to 2500 RPM. After 2500 RPM though, the AFR goes back to normal and everything runs just fine in the higher RPMs.
I've tried swapping the ECM with two or three other working ECMs. Swapped coil, distributor, MAF, spark plugs and wires, and the PRW-2 ignition module.
What else should be checked?
have the same problem?
