well, i have an update of sorts. Not more dyno figures but I did go back to the 1/4 mile track.

on 15psi with 20* total timing I ran 12.96 @ 113 mph 10.9 a/f
up from a 13.27 @ 111 on 13psi 11.6 a/f

question: do you guys that tune on a dyno see the same a/f on the street? So far that has not been the case for me. I had to pull fuel out to get my a/f in the 10.9/11.0 at WOT going down the track compared to the dyno runs. This further reinforces why i do not like dynos with turbo cars. With all the datalogging devices available I see no better tuning tool than a flat straight stretch of road with no cops on it. But then i see that as a good thing while tuning or not
