Ok, i just recently installed gauges in my truck and i've read around and seen a few numbers as to what i should look for. Correct me if i'm wrong, Pre-turbo (in the manifold right before the up-pipe) EGT's i shouldn't go over 1250ish, now is that sustained? or short bursts of more would be fine? cause right now, even in my 80 econ tune i can hit 1200 within 7 seconds of wot... and the 140 tune does about the same.. but i've always let off as soon as it hits 1200 and it drops quickly. tranny temp, i shouldn't let it go over 220? around town its going around 160ish. Now for boost, i've heard the turbo won't hold over 25lbs but a short burst of 30lbs is ok?, in my 80 econ tune i can hit 28-30lbs and in my 140 tune it'll hit 30 and appear to keep climbing, but i havn't let it climb over 32lbs. pretty sure the turbo is crapping out, have pretty bad surge/flutter even if not pulling anything.. What are yalls thoughts? or, i thought i saw a page with all this info on it before but i can't find it again..
Thanks for reading, Mitch.
*EDIT* i went out and drove it today, in 80 econ EGT's will hit 1200 and stay there, until 80mph+ then it started to crawl a lil higher but i ran out of road to really see it lol...
