Two answers:

2. Varies with altitude (I'm boosting 12.5 at 5,000', sea level is 15-ish). If you're somewhere in between, figure 1/2 pound less than sea level rating for every 1,000 feet up, that should get you somewhere close.

It's all dependent on your altitude and the weather conditions (in general colder=more boost) however from what I've seen:

stage 2 w/ stock exhaust - 15-16 lbs.
stage 2 w/GMPP or aftermarket exhaust 14-15

I usually run in the 15's but the highest I've ever seen was 18lbs. at 7000rpm in 3rd with an ambient temp. of 3 degrees outside. Also, if you really want accurate boost numbers you need to get an Interceptor gauge because the stock gauge is hard to read and gets inaccurate at the top end.

PS-A rough calculation that works for the SS/SC is 1lb of boost for every 0.1" decrease in pulley size

i haven't had my stage 2 in the summer yet, but i'm like Herndon high SS. We've seen mid teens and low twenties lately and i've been hitting (average) 15psi... I top at 16.5/17
