boost problem
so i had my car out running today and i hit boost 2 3 gears and boosted fine when its cold then when the motor gets warm it sorta cuts out after 5000 rpm is it cause its running lean and i need to turn up the fuel its running at 45 psi and rasies to 50 or do i need new plugs do you think?

Got a boost gage? Wideband?
also if your running a 12:1 disc in ur fmu, im guessing its rising to a lot more than 50 like you said, do you have a gage on that or something? and the 255 pump could be making it even worse because it could be overpowering the regulators.. just my guess but i bet its going rich..
do you know how much boost you are running? what turbo setup?
