Hey, just saying hello, I don't even have a Chev truck, but this forum is the probably the most relevant one for my interests so here I am.
My Car is a 1990 Australian Holden Commodore (with a 3.8 buick v6) but I'm trying to get a turbo installed on it and to do that I have to learn some things from other GM turbo installations with similar computers. The 90' Commodore runs a 1227808 computer which is the same as a 1227165 but the Australian memcals run a MAP sensor so I figured a good MAP sensor to use would be the same one your trucks use and do a quick reprogram of my memcal to get it running fairly good or even better would be the whole computer that you guys run. Anyway I'll be around here trying to figure out how to go about this the best way and various of things about turbos
