none so far, to/from san diego for retune I got 18+ @ 65-70. Drive there has hills and some parts where its only 2 lanes so Im constantly on/off the gas. Thats also with the romping I did with justin. Ive tracked my mpg's since I got this truck, so once I get 3-4 more tanks through, I'll be able to tell if there has been any decrease for sure....but nothing noticeable so far.

good, makes me feel better about doing it one day. Not in the cards right now, but when funds allow I may drop one in. I'm still debating a DD anyhow. But things always change

15.1 (Babying it to/from work)
16.5 (To/from SD and city driving)
14.2 (Pure city driving, was raining so traffic on hwy)

Mine been holding steady at between 14.5 - 15mpg on 85% highway with normal driving. I used to do 16.5mpg all day 
have u emailed justin/jenna? im sure theyd be willing to give u some shit to have ur tuner look at.
Nerp. Weve just gotta play with my setup a bit, or I deal with it for now and wait until I get a bigger intake and/ or heads
All depends on your mods and how you drive it performance mods can make the engine more efficient but if u drive with a heavy right foot you will definitely eat more fuel

No just a 4.8 with built trans. Efans are in my room, tried to order cal speed headers but out of stock.
I actually gained MPGs on my 5.3L Tahoe when I did a cam and LTs. I did however have a mild cam good for a DD and a blower; I will caveat that I HATE lope, so it was nice a smooth but had a slight grunt. All depends on what cam you are running, as well as your TC, and headers.
