@steve99 - I cleaned out the MAF sensor and switched to a different brand of 93. I also just finished a set of track days. Would you mind taking a look at a log?

Also is it still worth doing a MAF rescale? It looks like my LTFT's are within +/- 4%, so that's good, but still seeing my AFR's running rich on WOT pulls.

Thanks!

Fuel trims may level out over time if you've solved the problem. Until they're fixed, you're going to lose a bit of power at WOT especially in the low end.

I'd be freaking pissed and demand a refund if a stage 2 tune gave me 3 whp with that list of mods.
No waiting on a ECU learning period, something is wrong with that tune.

WTF? I've helped a friend install a boss 302 intake manifold on a 2011 mustang and a tune, and my god even that needs time to learn on the first start up it sounds extremely rough almost a misfire and eventually the tune begins to adapt and learn the engine, its literally the same for this car......

Fuel trims ess than 4% is good they will vary a bit with large changes in air temeratures as some compensation is applied to maf vs IAT.

Dont rely on wideband afr reading uness yu have correct bosch sensor and cotroller fitted.

your afr and commanded afr pretty good only about 5% out but the oft guys offset the OL maf scale on stage 2 tunes a bit to make it run on the rich side for safety. If you have good fuel you could do your open loop maf scaling to get the afr a bit closer on WOT but you migh get knock s if you do maf scaling just keep an eye on any hgh rpm knock.

was a tiny bit of flkc but only less than 0.6 so ok.
