Hey all, I recently had a 7.5in vertex lift installed on my 2011 Silverado by a very reputable shop. Truck looks awesome but my mpgs took a major hit. Only fill up with premium. I know trucks aren’t known for stellar gas mileage but going from 15/18 to ~11 mpg is a killer. Truck specs: - 5.3L with Diablo afm disabler used to prevent oil consumption (it works). - 18x8.5 in wheels with 275/65 duratracs (nitrogen inflated). 2in spacers all around. - K&N air filter. - new plugs and wires with ~30k miles on them. - flowmaster super 44 dual exhaust. I’ve cleaned the throttle body and MAF. Hooked up my obd II and no codes. Other than removing the lift what can I do? Thanks in advance!

I just rolled over 30k miles on my cc4wd, '16 with the 5.3, and 8 speed. I have read more than a handful of people recommending getting a tune (usually when the warranty runs out)...so this is my first post about that...before I really start my research, I wanted to get some real life experiences and expectations... I get that i can make my truck run like a banshee...but I don't need a hot rod...I just want to get optimal power and optimal MPG under normal driving...I rarely tow anything...and I drive pretty conservatively... in my scenario...would you still recommend a tune? what can I expect to get out of one? is there any that are the best value, what about getting a tune off the shelf verses going to a shop and getting it done? if I lose any mpg's it probably wouldnt be worth it...so I need to at least stay the same or improve...so keep that in mind... any insight and opinions would be appreciated!

Yesterday I had to run to Phoenix and back for work supplies. My company truck is a 2016 GMC Sierra 1500 long-wheel-base 2wd with 5.3L V8 (former Uhaul truck). I used cruise control, I meticulously went the speed limit, and I used the air conditioning and stereo during the trip. More than half of the trip I was hauling over 1500 lbs in the bed. By the time I returned the dash was telling me about 25 mpg for the round trip. Manual calculations at the pump said 23.49 mpg. In my opinion that's very good. Here's the video:- 28 replies
