please help
 

I have just purchased a 89 convetable, it has a turbo motor, a spliced wiring harness and a n353 ecu. The oil metering pump is ok and the ecu is also. It seems to be in limp-mode. Runs terrible, very rich. I have already fried the 353 ecu that was in it and replaced with the same. Can a 353 run a turbo? I have seen a lot but this one is killing me. Please help! Thanx! :wallbash:
