did the full turbo 2 swapp on my 87 na, except for the harness. my turbo 2 harness was hacked when i recieved the motor and trans. so i just modified the na harness. the engine runs great on th na ecu but when the turbo 2 ecu is pluged in it d=seems like it looses a rotor at 3k rpm. little help be nice. oh and i have read the faq many times but just havnt foungd my answer yet. any one have a write up on the harness modification needed to run a turbo 2 with a na harness? thanks a ton for any help. chris

 

sounds like it's taking a dump when you hit boost. it's probably adding an ungodly amount of fuel and bogging it out. what AFM and injectors are you running?
