The tailpipe sniffer isn't a good place to get readings from. The reason they were a full point leaner is because their sniffer was picking up ambient air. Also, to answer the question above, you shouldn't have to worry about the air density causing you much of a change, if any at all. If you were forced induction, it would be different, but not so much with N/A. Normally, when I tune the N/A cars, they come in for a one shot deal...unless they upgrade again and need a retune.

re:

*sigh*
i'm not gonna try to back anything i said on a this forum...
but that guy is a pro-tuner, so u can go off him.
sounds like a WOT tune more than a tune for a daily driver, but w/e.

i used sources like the book, rx7 forums, mr2oc, supraforums and their vendors, and other 1jz companies that were willing to help get #'s from the gt4067'd 1jz.
