Yeah, about 17 psi on pump gas. On race gas I maxed out the 14b on the stock pump and injectors, running mid-high 12s at the time. Just a point of reference. It really does pay to have a datalogger to keep an eye on them if you are planning on pushing their limits. From my calculations, assuming pump gas with a specific gravity of .76, and a target AFR of 11:1, the 2g pump rewired (see vfaq) is good to 40 lbs/min at 15 psi (not possible on a 2 liter, so suffice it to say that it will do just about any setup at 15 psi) and 27 lbs/min at 30 psi, which is pretty weak. For numbers in between, just work it out linearly. For 20 psi I would expect a capacity of about 36 lbs/min, and at 25 psi, about 31 lbs/min. This may not mean anything to you now, but as you search and read you will find out what turbos move what amount of air, and with a logger you can read airflow (only for 2g, or 1g with DSMlink). But at this point I'm probably just rambling again.
