All I've got is a Superchips programmer and I get 17-18 on the highway, and about 16 in town (I say town instead of city, mine's a little less stop-n-go)

I average 17-19 hwy, and usually 14 city. If the bully would guarentee 25mpg, I would have already bought one! I have hypertech chip, K&N, and
4" exhaust....

350 short bed 4X4 w7.3l, I get 19.7 to 21.9mpg city/hwy dirving. I bought the truck used and it had a Banks OttaMind chip (don't know much else about it) and a TransCommand under it. Am getting a AFE stage 2 with the PRO GUARD 7 cold air intake tomorrow and can't wait to get it. They say 50 hp and 112 torque. Also they say a 2 to 3 mpg increase. We'll see if it does make a difference over the next few tanks. And if it does :ZigBang: .
