Here's some updated pics with my Aeromotive Adjustable Fuel Pressure Regulator...
I ended up ditching the plenum because there was no way that it was going to fit with the FPR. Good thing I already had the parts to eliminate it.
Pretty much no clearance.
Another angle.
Purdy FPR.
Also, while I still believe using the plenum is the best setup, my new setup has very good idle and throttle response. I think that the multiple bends right by the MAF in the old setup was really screwing things up. You live, you learn.
