I had a economind and it was ok but when I switched to ATS/PPE tuner what a difference, but save up a bit more and buy EFI Live, my truck has never run better! Im sure theres more guys on here wishing they went straight to EFI also.
im going over to efi live only becase im putting a bigger turbo, injectors and a lift pump on my truck. and the guy i talked to on here said i wont get full use out of the upgrades. if i wasnt doing that my banks makes me more then happy !
