What tune to use.

[bandit0289]

Good afternoon all,

Background on parts:

Perrin intake, smooth intake kit, OFT UEL header, SPEC-D 2.5 " exhaust, light weight pully kit, OFT tablet.

I run 93 octane all the time. I flashed stage 2 UEL 93 oct. Car runs good, but feels sluggish. Posted up a log file, and the consensus was that You're getting minor knock at somewhat high load, nothing too bad. If you want to completely eliminate it, you could try using the 91 octane tune, or finding different gas that might be better. What fuel are you using?

You also have similar high LT fuel trims at light throttle/low rpm like I do with the stage 2 uel tune, how many miles have you driven on the tune so far before doing that log?

Long story for question. What is the correct tune to be using for the parts I have installed?

Thanks in advance

You only have 2 off the shelf options.
The 93 UEL and 91 UEL.

You can continue using the 93 or do as your post says, use the 91 if you're concerned about the knock.

If you're getting knock, I would flash the 91 tune and run 93 octane.

What about scaling the maf?

If the OFT Tune is not working for you you should get a custom tune. I would start with the MAF scaling and then start looking for knock.
