In my 2005, I found the Level 2 canned tune gave me better gas mileage and gave me much improved passing performance. (Which was what I was looking for.)
I don't know that you need to be "light footed". Longshot, buddy, I'm not arguing, but why did you say that? It's my understanding that the canned tunes are completely safe for any "stock" truck (i.e., not blown, no aftermarket CAI, no long tube headers and/or no X/H pipe dual exhaust mods.
