Hey guys,
Just got my 180 on the dyno yesterday to check its afr and boost settings re-tuned. Well, i got 158kw with FMIC, exhaust and airfilter on my blacktop
now, strange thing was, my tuner was saying the computer or afr mixtures where playing around, usually when boost is upped on sr20's it runs richer, true or not? well thats what my tuner said.. anyway. yeah he had tuned up the boost to a safe 12 psi ... ran it a few times again WITHOUT touching the boost controller . the afr raised and raised to from the 11.5 mark to the 13 mark after 4 runs .. WTF is going on??? .. anybody else got weird afr readings???
