Looking at buying a 2012 386 Pete with isx15, has had egr/def “fix” done on it as well as a recent inframe. Owner also state truck has 625 tune, and it seems pretty legitimate cause I have driven the truck.
My question is how high can I push this engine, obviously a non vgt would be a given. But as far as what size compressor/turbine, and what is safe limit for this engine. Don’t ask the Cpl, as I don’t know it but I believe it was a stock 550. Is 750-800 viable for decent life span?
