I have aquired a donor 88 suburban and plan to put the TBI 350 in one of my 715's. Searching painless's site and the web in general, I'm not really seeing an easy way to avoid using the original PCM from the Burb. I was hoping to eliminate a lot of the unneccesary electronics/emission stuff. I don't really want to install O-2 sensors and all, but it may be completely neccesary since I'm a little ignorant in this area. Anyone got any advice? Thanks, Bill
