Tuning on a supercharged 911.

[axl911]

I have a supercharged 993 with the 3.6 liter engine. The Eaton supercharger puts out 5.5lbs of boost. Unfortunately, I don't have access to the aftermarket controller that comes with the supercharer which changes the timing and fuel to cope with the superchanger.

It is currently running rich at 10.5-11 AFR (I guess to be safe). With a/w installed, I am very limited in what I can do to make best use of a/w. Can I simply up the boost to about 6-7 psi as a way to increase AFR to make best use of a/w? My concern here would be that I don't have access to change the timing.

Your suggestion would be appreciated.
