hmm... after your responce I seeked some professional advice. I know some drag racers and they said most vechicles do have the timing set back untill somtime after 3000 miles for break in reasons at which point the timing advances and it will be a noticble thing, but they said that WOT is not ever closed off...

So the question still remain open - has anyone noticed a difference in performance after 3000-3500 miles that has not altered their chip..
