is a programmer worth it?
SCT's come with canned tunes, though you can get custom tunes. [MENTION=99933]Franchi Motorsports[/MENTION] can give you an idea on what improvements the canned tunes will do for you.
I just installed my SCT Livewire and there has definitely been a difference. I have 295/70/17 trail graps on it now and before the tuner you could definitely feel the tires making it sluggish off the line. Definitely has brought a ton of life back to the truck even with these bigger tires on. I cant believe I didnt buy one sooner.
