What's the best tuner for 15 mustang GT PPG

[Genxer]

Just wondering why you have a VMP 91 octane tune but then run 93? Why not get a 93 octane tune?

I tend to be conservative, and like to have some margin. Besides, the car runs well enough now that I can't put all the power down in 1st and part of 2nd gear without spinning.

Something else guys, it is common where I live for all gas to contain 10% ethanol. Is this common around the country?

Yes EVERYWHERE in this country - up to 10% ethanol is a standard.

Steeda tune & cai is a really good and safe choice for a great price!
I went from stock to pp1 to Steeda and noticed a really nice increase in power and drivability with Steeda tune.

Not "up to" unless you believe everything the government dictates. There is no strict parameter for alcohols as there is really no decent self-monitoring even at the blend level. In CA, 10% advertised could mean more content.

I chose the PMAS "no tune" initially. I wasn't sure if I ever would mess with the computer, but a few months ago pulled the trigger. I switched the stock MAF back in and tuned it. That said, I'm not in love with the newest design of their heat shield, however their product flows like a boss.

A lot more people probably run a JLT vs the PMAS, and they are completely satisfied. But... you do have to run a tune with it.
