I'm sure this is obvious and I think I know the answer but here we go anyways:
I'm to the page where I select what tunes I want. It shows the stock calibrations as I have just an EVO. WHere it shows Level 1, Level 2 etc... I just select what stock tune that I want over written correct?
I am looking at getting an 87 performance and 87 tow.

What have others used for each level? Do i keep the 93 performance or canned tow tune.
Current Suggested??
Level 1 Transmission custom 87 tow
Level 2 87 Tow custom 87 performance
Level 3 93 Performance keep as is?????

Sorry for the questions, I just want to get it right.

Thanks for any help.
