Help with what exactly?

You didn't say what problems you are having?

I see you left a few things on with the no cats. COT is still on, turn that off. The cat test and post o2 sensor test in the engine diags exhaust tab are still on, those need to be shut off. But if you are running a newer version of the software you probably can't see those tables anymore.

The data log is missing lots of stuff. Add cylinder airmass, knock retard, injector pulse width avg for both banks, commanded AFR. You also need a wideband oxygen sensor for tuning.

Power enrichment is still stock, going to want to bring that in way sooner. It'll unlock some power because right now it's still has the 8,000rpm delay and needs over 87% throttle to do anything.

Sorry guess I didn?t go into it too much
It?s messy, the throttle doesn?t kick In very fast.
And it has less power than factory im assuming because of the o2s being so far back.I?m new to the tune game and need some help
