It vaires a lot from car to car. In 6th gear in cold weather mine hit 19.9 PSI (1.4 kg/cm2 on the GReddy gauge) with only the RMM DP and GT Spec. All else was stock -- no cracked or pulled hoses, no bleeder T, nothing. I've heard from a couple others who had the same thing happen, but most are in the 16 PSI range. Of course you'll have to have a BCC (or equivalent) to prevent fuel cut and allow you to sustain higher than about 13.75 PSI.
I was hitting around 1.0 kg/cm^2 with my downpipe w/hi-flo cat and TRD. The downpipe is the best HP/dollar mod out there other than the bleeder-T. Nothing can touch the bleeder-T, 60+ HP for $2!!!!
