Stock ap2 pulley on ap1 making (9psi) with (intercooler) and only (240whp) to boot. Is it just me or is there about 3 things that don't add up right at all. What am I missing here The only thing that makes sense to me with your set up is you should be at about 6psi with your current pulley situation and with your intercooler you should be down to about 4 psi and with your lower compression pistons thrown on, this all should get you to right about 240whp. My first advice to you would be to pick up a new boost gauge. You could call that your boost problem.
