gas mileage build

well my leaf springs are shot so I'm orfering new ones in a week or so. I'm getting alcan's built to haul about 350# all the time and putting a timbren kit in the rear. The springs should give me between a 1-1.5" lift. I'll be getting billy 5100's for the front to level it out. But that's the stuff I need. I still have to buy the stuff I wanted to get this month anyway. So I'm also getting a maf calibrator and rear sensor simulator (so I can pass emissions because magnaflow lies about theire HF cats being obdII compliant). My afr gauge is on the way already. I'll post some pics after I have the lift on.

 

Oh and my hood w/ hoodscoop is getting picked up next week so I'll have that on too.

 

i average 28 highway in my 4cyl. ALLLL stock too thats doing 75mph too

 

I've got 215,000 plus miles on an old, beat, 1999 4x4,2.7, reg cab company truck. Still runs great and with no hesitation would drive it across the country. I've got fuel records from day one. She gets 24 on the highway, 22 in town. Stock except for header and highflow cat. I get an extra 2 mpg(24) if I leave my mountain bike in the bed. It must break up the vacumn flow behind the cab in the open bed. Tryed it with the tailgate up and down. Gate makes no difference. Just looks stupid with gate down.
