Maybe try pasting half again and see what that does and do you have your tune so we can look at it?

Changes to a tune can sometimes take a good 100miles or a day or two for everything to settle. A PCM reset can zero trims but adjustments to the air-side (Throttle Cracker, Follower and other air adjustments) will need a period to re-learn.

You aren't in SD, so you shouldn't be changing VE for trims. The MAF is boss until you turn it off.

The MAF is reporting in your log, I may be mistaken, but it LOOKS like it's active. As long as you have the DTC to show you are in SD you are ok.

my maf has to be off, when i set the fail freq to 14000 once again the car looses all its power, when its in SD it has way more power. I need to figure out how to log the maf and learn to tune it.
