ThunderMax EFI
Good or bad?
My ECM is bad and needs replaced. Should I go back with a stock $400 ECM or the $900 ThunderMax that auto tunes?
TMax has a 3 year warranty, stock ECM warranty is gone when I open the package.
TMax users, are you happy? Good performance? MPG?

I'm a happy T-Max owner. I would suggest that you go with a T-Max IF you need some sort of adjustable fuel management. In other words, if you already own a PC or SERT, save the extra money and go OEM, but if you need to adjust AFR's and timing on your own, you'd like T-Max.
