Has anybody tried both the 93 tune from Evolution Performance and the 93 extreme tune? What's the difference between the two tunes? If I presently have a JLT intake and the 93 tune, is it worth upgrading to the 93 extreme tune? Are there any restrictions or drawbacks to running the 93 extreme tune? Thanks in advance for any advice or info.

 

+1!!! Good question. Wish somebody could give you an answer. I'd like to know myself.

 

I don't know. However, why don't you just call Evolution?
