Ya Just Can't make a SMALL BLOCK perform like a BIG BLOCK!, Diesel!, Or 1 Ton..(Ya Get Spoiled!---I DID Anyway)....I've Had the D-Max dually, Cummins 24v Dodge Dually, GMC Dually w/6.5L...and a few Gassers along the way! (worked THEM Hard!) And, As I'll ALWAYS Have a GOOD Work/Tow Rig....
CUZ My 2 JUST WON'T DO! 
(Said my piece on the towing abilites of the H2 through the years...Any other comment is best left for the search link.......Nuff Said!
)
Got A Whapping 15K (bought New) on the 02 CC Silverado LB, 8.1L w/Allison...A...Get-er-Done!....Pick-up.
....Just For That Reason!
Anyway, JMO, Get what you can with the programmer, back off the pedal, and enjoy your ride!-----Of ALL The Cruise Controls, (in ALL the rigs I've had anyway), The 2's...ARE BY FAR THE MOST RESPONSIVE!...It's programmed to Maintain SET SPEED--No Matter What!....And as you keep track of it, and allow it to work!....You Will Find...IT WORKS VERY WELL! No Choice! ;-)......ALL The way to 2nd, huffin hard in the hills, I think I Can, I think I can...30mph!.....NOT!...WELL!
