looking to buy a new tuner and very up in the air between something i have used before and something that seems to be the new big thing. my first 06 made great power with the smarty and a drop in filter with an airdog 165. i have basically the same set up on this one but with a somewhat built auto trans not sure if i should go back with the smarty or go with efi live. i tow drag race and sled pull some so i need an all around tune. just looking for opinions on best direction.

 

You don't needan aftermarket lp...unless it's already on there. EFI live is easily superior to smarty. Why get anything less than the best?
