here's is the link to my log
i had the lo-throttle set to -2 from 800rpm-3000
my Lo fuel trim didn't go up from 85%. and when I did try to lean it out it didn't move the low trim didn't move. also when i stepped on the throttle to the 5k mark i was at 13 lbs of boost then as i let off the gas it car stalled.

Pretty easy to read log SETUP<- but possibley the worst log ive ever seen. DO a THIRD GEAR pull. and are you recirculating your blow off valve? If you are NOT and you are wondering why your car stalled then you simply need to read some of the newbie treads about venting to the atmosphere. 3rd gear pull and we can help you out some more

Should not have to adjust much if you're Stg3 was properly calibratred to your 2G MAS, 650s and 38psi base FP. Mine car only needed +/- 2% to get trims near perfect.

When I tune my fuel trims I datalog Oxy-Feedback (ST Fuel Trim which updates your LT Trims) and the three LT Trims.

You should see a smooth oscillation with a midpoint near 85% in your current tune. By decreasing your SAFC's fuel correction at each reference RPM (while in closed loop operation, i.e. constant RPM) you should see an immediate impact (midpoint will rise). Keep adjusting the SAFC until you are near 100% and then take for drive and see how your LT trims look

i'm not venting the bov. It's recirculated back into the intake. i tried a third gear pull but right after it died once i let off the gas. i'll post the log when i get the chance. thanks for the responses
