Right now I'm at 420RWHP with these mods on my 2006 GT, Saleen SC, 3.6 pulley, JDM Tune, Autolite HT0 plugs, 39LB injectors. Right now I'm at 7.5 PSI. The 3.4 pulley would take me to what psi, and how much horsepower will I get?
Would this be safe for the fuel pump and the stock rods and pistons.

with the 3.4 pulley you would see between 9-9.5 lbs. boost, it would bump you up around 25 ish RWHP putting you in the 450 range.

A boost-a-pump is reccomended at a mimimum, but you may want to consider the GT500 fuel pumps also.

I ran that combination for a year, but recently swapped tp the 3.2 pulley and 60 lb. injectors.

Still on stock internals.

+1^ You should already have at least a BAP. It will be good for those power levels and pretty safe on your stock internals.
