make sure you get a custom tune for those LTs or you wont get much of a gain.

LT = long tube headers. And custom tune, not canned.

No need for a custom tune for LT's alone. The reason why you would is because the O2's are relocated further downstream. These O2's are self heated, via PCM. Yes, it may run a tad lean for the two valve, but not enough to warrant A/F dial in, not by themselves.

You can acquire a canned set for shift point changes. Info from Troyer articles on this site and my own video logging.
