well got some tuning done now i cant make it run any richer than 12:5:1 but timing is advanced 6* and i got the shift point changed from 6500 to 7000
8 psi with m62 and IAT under 100
Fuel pump?
I maxed mine out at 6lbs...
Threw the Racetronix in, BAM.. sub 10:1 ...
ya, had to lean it out a bit.

At what part in the RPM band is it hitting 12:5?
So you added 6 degree's of timing on top of the stock file?

not unless ur knocking from unsufficient octane levels. 110 will allow u more boost and timing but if ur not changing the tune than leave it what u run.
youll want mid 11's for afr , when mine ran in the 15's and touched high 14's , the afr was right about 13.0 , once i got the afr dropped to the mid 11's it knocked a good half sec off my time
im guessing your missing alot of tuning , i took a friend of mine a couple weeks to figure out the early g/a tune and got it to keep mid 11 afr's , before it would run all over the place
untill then you might want to bump the fuel pressure up , tell you can get the tune to keep the afr in the 11's
100 is more than plenty , 110 is a waste , not to mention you make more power the lower the octane rating is , provided you can control the spark and get no knock
i want to but my injectors are pretty much maxed out now. i run 12.8-12.5 afr now it will not go any lower

at what fuel pressure ?
i know the 96-99(might even be 98) ran 41-44psi , and the 00-02 ran 51-54 psi , if you are at the lower pressure range you can bump it up , but i would do it 2 psi at a time , just leave room for the pressure to raise once it goes into boost 1 psi of fuel pressure to 1 psi of boost
well im heading back to the track this friday just wondering if there is any tips really for getting a good launch in a auto
