IMO canned tuners work for alot more than just the average joe, lots of daily driver, race and tow rigs run amazing with canned tuners. BUT, like the sticky says, if you have very specific expectations from your truck, go with EFI. I hear great things about Idaho Rob and im sure that there are many EFI tuners that have great tunes. All depends on what you want and what you use the truck for... Good luck!
