I just picked up an auto 05 G35 last week with a stillen stage 2 kit and was wondering what my a.f.r is suppose to be at? Its reading around 14 right now at idle. also I know nothing about widbands and was wondering if I need to adjust anything. Also what is the vacuum suppose to be at idle? its at -10. I fell the car is a bit slow for my taste what would I need to do to make a little more power? what do I need for stage 3 pulley and where can I buy it?

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

 

Stillen is weak sauce for this platform, it is known for its low power potential.

AFR at idle is not worry some at WOT is where I would be concerned. Google AFR and do some reading now that you're boosted it's something that you should understand.

If all else fails Stillen would sell you the parts for a stage 3 but from what I have heard you won't see much difference in power. Go right to stage 4, google that and I am sure a list of companies that sell the parts will show up.

 

well I am very concerned about what the vacuum is suppose to be at cause I think it may have a boost leak
