so im just curious what all my fellow 5.7 guys get in there trucks with or without a tuner??

 

i have a 07 quad cab and i get about 13 average around town don't do that much highway driving but its around 17 the last trip i went on, i don't have a tuner or anything just a cai and i just switched to a magnaflow from a flowmaster 40 series

 

i really depends on how I drive, it varies from 11.5 to just under 14. No tuner, but I like to drive it like I stole it more than I like to baby it.

 

12.5-13.5... I drive 30% hwy, and 70% city and usually pull a boat at least once every tank... i usually dont drive it hard..

 

My read-out displays 11.3 religiously, but i do a bit of towing my utility trailer around. Highway, maybe 17mpgs and 13city normal
'08 Ram w/91oct Predator tune with MDS turned off.

dedogg, you don't know what your missing with a Predator tuner. Partial throttle upshift, shift enhancements, no MDS shifting delay or flutter sound from an aftermarket catback.

 

I know it finally came in just waiting to pick it up. I have a buddy that buys direct from the manuf and gets one hell of a discount. My headers and magnaflow mufflers should be here this week and I just ordered two cut outs. Its gonna be a fun summer.

I pretty much drive 50/50 highway/city and I average about 12.4 mpg. Just got a tuner and installed 2 days ago so we will see if that changes.

 

93octane tune with no MDS, K&N drop in filter and Magnaflow cat-back, 70%hwy, 30%city I average about 18mpg.

Towed my 2700# trailer to work the other day to weigh it, got 15.3mpg towing it.

 

Just switched to 87 tune running 89 oct but my last tank I had a 91 tune in...getting about 15 city 22 hwy normal driving. With the stock tune I got closer to 24 hwy going 65mph believe it or not.
