Some smoke at WOT after header install & O/R pipe? Is this normal, I've noticed a puff of smoke right before the shift at 1-2 and 2-3 at WOT, it looks kinda blue, but my windows are tinted pretty good and it's hard to tell, the car also smells very rich or so I think it does?

When you floor it now, your ECm puts the normal amount of fuel in plus the 15%-20% that you get from being lean at part throttle. That is probably the smoke you are seeing - you can chaeck for black soot too around the tailpipes too.
Yo can fix it with a MAF translator or ls1edit. You should definitely use a scan tool, though, and best with a dyno.
Good Luck.

Re: Some smoke at WOT after header install & O/R pipe? I have the dual/dual stainless catback which I usually keep really clean by polishing, as of late (since the headers) they are just plain black with smutt and very hard to keep clean! before they would stay clean for a couple of weeks, now they are dirty after 1 day!

Re: Some smoke at WOT after header install & O/R pipe? Anyone else have this problem? the smoke is not blue, I have checked a little bit better and it just looks like road dust, but it is smoke from the exhaust. it only happens at WOT in the higher RPM's.

Mine does this also, I was on the freeway running with this rustang and I had to feather it into 4th(factory tune) and when I looked back I saw smoke, but car was good so I kept pullin on him. I also didn't notice it til after I put my headers on. Id say its pretty normal
