Working thru tuning my Gen 3 turbo 2 bar build.
Failed the MAF and setup OL
Tuned the VE tables to a reasonable point up thru ~10psi (street tuning)
Flipped the MAF back into play and left it in OL
Touched up the MAF freq table to a reasonable point
AND here comes the weirdness
Put it back in CL took it out for a ride and when I hit boost it remains lean. This was not what was going on when I was in OL. This is my first tune and I was feeling pretty good and could not wait to set it to CL as I thought it might clean up the tune a bit more. Guessing I did something wrong, any tips on what to look for/change/??.
I have enclosed my tune and log. You can see the condition occur in the first minute of the drive, you can also in the second minute if I roll into the boost soft it seems to be better.
Any advice would be appreciated.
