If you don't mind I'll answer you with a question.
What octane gas do you run the most of?
If your answer is XX then go with XX octane performance tune.
If your answer is YY then go with the YY one.
It's that easy!
Personally I run 87 octane. So I went with the 87 octane performance tune, plus a performance tow in the same octane also.
Kept the 93 canned tune level 3 incase I ever wanted to spend alittle extra on gas and have some fun.
IMHO
I also feel the gryphon is a great building block incase I ever do a s/c.
