help! motor wont rev!

[salt1o1]

so i just finished my jdm motor swap on my 89 t today and fired her up. she ran great and idled like a champ. went to test drive it and she wont rev past 1500 rpms. every time it hits 1500 she bogs out. we were figures that the cps was bad and it was sending a singal to the ecu that the motor was raving high then it should. like hitting a rev limiter. so we tried a different cps and still no luck, it ran worse.

any one have any impu ton this?? what should i try.

You might have boost leak some where, recheck

Check for boost leak, check for engine error codes, check the ECU ground on the intake manifold. If none of the above replace fuel filter if you never have.

check your AFM, make sure its plugged in
