Just had wideband installed and at cruise I'm at 14.7 but wot I'm at 11.2 for a split second and then bottom out at 10.0 before redline. Fixing to install stealth pulley and volant cai tomorrow. Need more info on routing supercharger boost vacuum line into intake to draw more fuel.

What size of pulley? Same as the statement you quoted?

If so you should be fine with just swapping the pulley and AFR's won't be to rich as they are now

Thanks for reply. Correct Urd 2.85 stealth. Anyone have instructions on the supercharger vacuum line reroute to draw a little more fuel? Dealer was cool about cai and stated they didn't care, but if I switch the 255 pump that might be an issue.

I tried the simple FPR mod of attaching the vacuum line from the intake tube to the boost port for about a week - however I didn't really like the throttle response change that I got from it. For me it seemed like power, while feeling more linear, was slower to come on with throttle input. I put the line back on the intake tube and I feel my setup that way gives me the best throttle response.

Can someone explain how this mod is an advantage? Normally the for gets vacuum only from intake correct? How does sending a positive pressure affect it?

My 2010 with s/c runs full rich at wot and I would like to slightly lean it out, already running 2.85 pulley and volant CAI with ram air scoop

Normally the FPR sees neither vacuum or boost.

I would completely explain everything over again, but right now, I just don't feel up to it. Your question has been answered in the link that I posted.

Read the entire thread but don't understand why I would need more fuel pressure if I am running full rich...
This mod seems to increase fuel pressure/flow right?

I don't want to be running full rich... And already am, so I don't want more fuel pressure...

You understand the part about being an '09+ then correct?

This mod increase what you said, so that you increase the effective flow rate of the injectors so that they can support a little more HP, with out hitting MAX IDC.

Basically, add a 2.7" pulley to get more air, or get a wire in aftermarket ECU of some sort that will allow you to tune it for proper AFR's.

Can u recommend a wire in ecu?

Also I have seen folks getting well over 400 hp... With boost well above 10psi... At what point do I want to stop gaining power as to keep the longevity of other components like the transmission?
