Need Help

[RabidC]

I have an 1989 Suburban, 350 TBI/ 400 turbo I just rebuilt the drivetrain....took it .030 over, cam, etc. The problem I am having is that the computer is staying in open loop and is dumping way to much fuel into the engine. What I am looking for is a programable performance chip for my truck. Any help or suggestions would be greatly appreciated. /forums/images/graemlins/1zhelp.gif /forums/images/graemlins/burb.gif

HyperTech could do this for you. There are a few other companies too but I cant remember them off of the top of my head.

Put a 195 degree thermostat in it and check the sender for the ECU.
