Leaning out at 10psi?
 

I usually don`t need to ask questions on here but here goes......I`m running a majestic stage 2 turbo, rtek 1.7, 550cc pri, 720 sec, 2.5 fmic, 2.5" rb exhaust, safc and a walbro fuel pump.....I`m running lean at around 5000rpm 10psi boost safc is set at 24% fuel at 4500rpm, 30% at 5000 and 32% at 5500....I just can`t figure this out...i`m gonna put the 720s in the pris and buy 890 sec.. Any suggestions?

i been having trouble with my rtek except with it getting rich from 3K to right before the secondaries kick on... i really wonder why you are running lean since its only a stage 1 turbo?? AFR readings??

what are the AFRs?

i`m currently running a narrow band A/F guage so I can`t give you a number, but at around 4700-4900 it goes super lean, falls flat on its face...i`m clueless!!!!

try replacing your fuel filter?? you shouldnt need to add that much fuel and have it sitll run lean.... somethins not keeping up....

yeah, i`m gonna try that tommorrow..also might change the fpr. I tried to call majestic and ask them what was max boost on this turbo, but i just got the run around. I changed a few things on my safc.......@3500 18% fuel, 4500 22%, 5500 28% @ 12psi...it came out of the red on my A/F guage, now is on upper side of yellow/green....my safc low throttle is at 86% high is at 94%.....it registers between 79% and 96% at wot.on recall. It is hook up via boost pressure sensor...is this thing toast?
