How long does it usually take your trans to shift good after switching to KEM tunes? I went from the canned H&S tunes that come with the Mini Max,(Which ran very nice in my truck), to the KEM 310. My truck didn't shift good at all. Should I just give it time to re-learn?

I did a re-learn, but not what I'd call a good one.:doh: I'll try it again tomorrow. Is the 345 safe on a stock trans and headbolts?

I run 310 all day, 345 is a lot better on the trans. I would change to 345 but I feel like swapping tunes gives you a chance for some trans relearn flare. But I know that is probably not the case.

For the head bolts, I would just drive smart on it. It feels like it has a lot safer pull when cursing on the highway and stomping it 65-70+. I never get flare and rpms are in check since tc locked. Your more susceptible to screwing something up at lower speeds. Just check egts.

Yeah that or a p0000, think that's the code, is normal in the 310. Mike said it'll only happen in that tune.
