One way or another the LT's are going on this weekend w/o cats for now, also I should have a new Ported TB coming in sometime next week. Now I know the LT's are going to lean it out a bit, and I thought I heard that the ported TB can lean it out as well. So how bad do you guys think its gonna be?

 

No way to say without a wideband. I would guess "a little" but not "a sh1tload".

 

Well the wideband will be going in at the sametime as the headers, I've just heard a few different people saying that with that combo it brought it down to the point they were either throwing codes or about to.
