I just picked up an auto 05 G35 last week with a stillen stage 2 kit and was wondering what the vacuum suppose to be at idle? its at -10.Also 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?

 

It should be at -20 at idle. Check for any obvious leaks or get a smoke test done. The Stillen kit simply doesn't make that much power, either swap it out with a Vortech kit or ST/TT setup. Most people go straight to Stage 4 with the Stillen.

 

so the car being automatic has nothing to do with the vacuum siting at -10? also where can I find the stuff to go stage 3 or 4?

 

They have vendors here that have stillten that can get you up to stage 4 just check the engine thread and make sure you research everything first

 

^+1. And being 5AT has nothing to do with it. I have a 5AT with a Vortech and I idle at -20 vacuum.

 

alright and will this boost leak affect my AFR? It drops below 11 with just a little rev

 

Yes it does affect it, you need to get that fixed ASAP. What RPM do you idle at?

 

let me check. and thanks for the help

 

its sitting at 500rpm. and no leak now. it was a bad boost gauge. but the afr when I rev it a few times reads lean???? is that normal
