Put the new T3/T4 on the other day and hooked up my new LM-1. Was running in the 8's and 9's under full boost with 40 PSI base fuel pressure. Dropped to 37 PSI and in 9's sometimes 10's. Also while cruising im in the 9's sometimes. Right before i parked it, it got in the 14's. Should i go lower? Also have a couple exhaust leaks in front of the wideband: V-band and flange to the turbo. The reason i ask this is because i thought with stock fuel injectors and more boost it starts to go lean in the higher RPMs. Here's some video's so you can see whats going on.

you need to tune that thing, you should be in the mid 11s to low 12s

gas for that thing is going to murder you

i hope you do not have a catalic converter, its going to get so clogged up running around that rich

are you running stock injectors?

Yea 35's. I'm probably going to turn the boost up to see what it does.

thats not your problem. you need to tune the VAM curve, then once the VAM maxes out you will need to tune for that
