The AM 91 race is pretty darned aggressive. In my auto it will
bark 2nd and chirp 3rd at WOT.
The AM 91 perf does not bark 2nd for me, but it does shift hard and fast.
Having said that, I went back to my Bama (dougs) 91 performance
as it does not bark 2nd at WOT. It shifts crisply, but not to hard.
As others have said, try them all and have fun.

If you have an auto I wouldn't suggest driving on the 93 race tune for a daily driver. I love that tune but it's set for quick accelerating shifts not stop and go shifts. At least that's my opinion after driving with it for thousands of miles. I use the 87 street tune and I love it. For events/shows I'll bust out the 93 race but that's all for the fun!

I gots a manual, so the shifting is all up to mee

The nearest shop ive seen that sells 93 is a half hour drive (One way.) Plus ive heard its really 91+ Alcohol, so its not a true 93 :/ So I ordered all 3 tunes for 91, keep it nice and simple at 1 octane

1 octane for all your tunes is fine if you're sure you can always find it. I travel with the Stang frequently (but she's not my DD) and I've had at least 2 occasions where I could only get 87 octane. Both times I was in Bumfuk after midnight with less than 1/4 tank. Fortunately, I have an 87 custom tune and keep the tuner in the car.

Good point. In that case I may ask bama for an 87 street tune... god bless that free tunes for life program

I have an 87 tune and the only time I use it is when I travel for availability reasons. If you had a 91 tune around here, you would be SOL...mid grade is 89.
