stock 14b
stock 450s
3in turboback mandrel bent no cat
wal255
rewired
aeromotive afpr - 38psi
fidanza flywheel
exedy stage 2 clutch
KN filter
hacked maf
modded 1g bov (not crushed-the extra nipple)
mix of 4g of 91 and 4g of 100oct
fuel trims were like 139low 103mid 105high

ok i have one small boost leak, as in holding 20psi for about 3-4 minutes but does drop. the leak is from the turbo, not the intake or outlet pipe, its from where it connects to the catridge. anyways the most recent mods are the aeromotive afpr and 255. before i put in the 255 i was getting af of about 12.5-13 according to wideband. after 255 with stock fpr i was getting around 9:1 af, so i got the aeromotive afpr. after installing it i was not able to use the wb since the threads were f'd up by a friend using it. anyways i did some logs with MMCd 1.8 and basically whats happening is its backfiring like a mother####, only at high rpms. base pressure is set at 38psi, boost is not passing 10psi, im doing 2nd and 3rd gear pulls and im confused. someone helpz0r

and same deal, i know im not hitting 8k rpm, and also im letting off when it starts going backfire crazy. also boost controller, i have it set to higher then 10psi, but once it hits 10psi it starts going backfire crazy, the highest ive seen it hit was 12psi and when it goes crazy it will knock back down to 10psi

I would say that your running lean. Your O2 should be at .90 to .92.

only 10psi i dont understand :(

get your wideband working, narrowband 02 is worthless. you could try bumping your fuel pressure to squeeze more out of those 450's if you really are lean.

if your wideband says A-ok but you show knock on the logger, maybe the knock sensor is bad. put your hand back there and feel for goo. if you feel goo, time for new sensor, if the sensor can be twisted by hand, time to tighten it or get a new sensor.
