I don't see anything wrong with that log other than your STFT need some scalar tailoring for the grade of fuel being used.

If you are going to use PTF I believe they will tell you to set your log parameters back to default and then add: "boost set point factor" and "maf req... ..." (There are 2 maf req, you want the one with the dots/elipses)

Looks pretty solid. You could mess with the fuel scalar a bit, but as it sits the car probably wouldn't hiccup with the current scalar.

Going to adjust fuel scalar and I'll try to get another log. Hopefully before I dyno this Saturday.

Log looks very solid. Unfortunately, looks like the torque is too much for your clutch and it's starting to slip. Time to upgrade

Log looks solid.
You have an inline pump and access to e85.
add more e85 ( i suggest you put e65) raise your afr to 12.5 instead of 12 and increase you timing too 14.5 instead of 12.

Will try it after I replace the clutch but this will not be for awhile. Hopefully I can get a good run at the dyno tomorrow. Then will flash it back to a more conservative tune to try to make the clutch last a little bit longer.
