I have upgraded turbos, my higher tunes also run cooler than my lower tunes when towing. Trans just isnt a big fan

2010 Chevy 3500 DRW CC 4x4 with dpf/ egr delete, K&N CAI, MBRP exhaust, custom efi tunes from Danville Performance. Unloaded on a recent all highway trip from Indianapolis to Atlanta I got 20.9 mpg on trip down and 24.0 mpg on trip home. All hand calculated. Towing our 43 Donzi (triples) from Punta Gorda, FL to Indianapolis I can get 11 mpg. Trailer and boat with fuel weigh in at close to 19,000 lbs. I love this truck

2011 GMC 3500 4x4 DRW Denali 6.6 duramax
H&S Black Maxx, delete, cold air intake. Everything else stock
HOT setting (OMG fast) empty 77mph 1800rpm 20-21mpg
towing8-12k 77mph 11-13mph
Mild setting (about 50hp) empty 77mph 1800rpm 18-19mpg
towing 8-12k 77mph 10-12mpg
If I drop down to 65mph (which takes forever to get anywhere) I can up my empty mpg to 22-24 and my towing mpg is around 14-15
I know my numbers seem unbelievable to some, but they are straight up fact hand calc numbers............This truck with a programmer and bs removed is the best truck I have EVER owned period. It has 80K on it (it had 33k when I bought it in Dec. of 2012)
Around town I average 17.5 empty.

I refueled when I got to atl ( was actually Villa Rica just east of ATL) to see how I did on trip down. I was only in town for a day at an auction. When I got back to Indy I filled up again to check how I did on way back. The trip was 546 miles each way. This was my DIC after I filled up back in Indy. This is as high as I've ever seen it, although it's never very accurate. Sometimes high sometimes low. But the 24mpg was hand calculated. [ATTACH=CONFIG]523195[/ATTACH]
