I'm honestly not even sure, I cant remember where I saw it but I think I read something about temperatures (of some kind) being a little high on the stage 1 tune. I think it was intake temps?
Yes, I realize how vague this is. Hahaha.
Lol
In that case, I would definitely say not to worry about it. The system has a few different temperature controls to reduce/eliminate possible issues, and the Stage 1 OTS tune is pretty safe overall. You'll see a lot of chatter and concern on the forum, but mostly from people that have no real clue as to how the system works.
Even high CAT's are basically a non-issue. Do you give up power with them? Yes. Is that instant car death (or even eventual car death)? No.
Watch your ignition corrections and do a few datalogs to get an idea of where your engine stands, but the FiST is pretty strong and I can't even recall a single failure by something other than warranty-causes (radiator issues) or stupidity (being full-boost on a meth tune when out of meth).
