you need to play with the main VE table. this is where you need to log and go about adding or subtracting in hte main ve table. playing with this adjustment takes time and time of logging. log for 20 minutes and try not ot go above 3500 rpms and make changes. you take each value of a given cell in the LT & ST and compare say if its +4 LT and -1 ST then you have 3 and take half of that and add that that cell in the main VE table. keep doing this to you 0'd out all your LTs
also if you want you can bump your PE delay up a few rpms.
also +/- 10 is considerd in the stock range of LT
also each day will have a different value on the LT. and its still in the learn process. one day it might be dead on the next it might be in the ball park
go into the HELP and it will explain more

It starts breakin up really bad and going into alot of knock retart. When I floor it, it pulls out of it and enriches both banks up. If I let off both banks equal out as well. I'm using HP tuners, and can't figure out why it would be doing that. Its also got the MAF disabled.
help?
help?
How far from the turbo?

I'm pretty sure when I'm part throttle its not boosting to the point where the waste gates open. Could be wrong though. Maybe I'll go for another drive and watch the boost gauge a little closer just to see.

I think he meant what throttle %. He shouldn't be in normal closed loop while under boost.
