Default possible boost issues

this might be a silly question, i am running 12lbs. with a procharger. it hits 12lbs when at 5000rpms (red line for now) then shifts and drops to 6ish lbs and climbs as the rpms do. so the question is is there a way to maintain 12lbs all the time once at WOT.

A stall converter will help keep the RPM's up while getting on it but other than that I can't think of to much.

A ProCharger without a stall is a whole world's difference than a ProCharger with a stall. Circle D, Yank, etc. Check them out.

pretty sure a turbo would have blown it up just the same with a tune that's out of wack

Its good your rich so your on the safe side, but a live person tune will def. help dial your combo in more.

A performance torque converter will help you stay in a " better" rpm range that will compliment where your blower is strongest/ in turn lessining boost drop and helping your combo get into and maintain max boost.

If your running a 60E, the yank TT3000 is a nice tight converter that you can DD and almost not notice it.
Also gear change would help some since those prochargers like rpms.
