don't beat me up too bad here, im very new at this. ive played around with hp before but never from scratch. I just bought a 2005 Silverado 2500 hd with the lq4. its basically just going to be my dd in the winter and a plow truck, so im not looking for crazy performance, but this thing is a DOG! very unresponsive,sluggish, and feels like the pedal has a 3 day delay haha. it runs smooth and solid just feels super lame. seeing as how im just looking to wake it up a bit and maybe help the trans last a little longer since im going to be plowing and towing with it, what should I do/not do? I didn't see any respiratory tunes I could get a baseline with, and I did a bunch of searching but didn't see much that wasn't ones looking to get the most power they can out. thanks in advance for any help
