G35 stillen help

[Herzog racing]

I just picked up an auto 05 G35 today with a stillen stage2 kit and was wondering what my a.f.r is suppose to be at? also I know nothing about widbands and was wondering if I need to adjust anything. I fell the car is a bit slow for my taste what would I need to do to make a little more power?

Just new to the g35 and want to make sure the supercharger and everything else is solid.

For boost applications, safe reading under WOT would be 11.8-12.0. 12.5 is the most ideal, but also on the border of causing detonation. In order to adjust the AFR, you would have to put the car on a dyno and have it tuned with tuning software. The stage 2 kit properly tuned should pump out at least 350whp. You really need to have the car put on the dyno and see where its at before you can determine where you can go with it power wise.

At idle its the afr is reading around 14. And is the vacuum suppose to sit at -10 when at idle? If not I may have a vacuum leak but was thinking it might be different for a auto g35

14.7 is considered stoitch and -18 to -20 for vacuum...
