Looking for more mods for gas mileage and performance

[ratt396]

Hey everyone, Looking for something else to help with gas mileage on my 95 f350 4x4 crew cab and performance. Right now I have a ts 6 position chip with tunes from tyrant deisel,around 85hp with the stock injectors is the most he said it would take.A S&B intake,oil is t6 shell with rev-x in it,also put the rev-x in the differancails last week. Like I said its a 95 7.3 4x4 crew cab with a 10" lift and 395/70-16(38x15.5-16) oh and a 3" down pipe and straight thru 4" exhaust.4:10 limited slip gears. Its got 206000 miles on the truck.I drive highway now about 30 miles each way and I figure out each tank I get an average of 12 to 14 mpg. So was wondering if there was anything else I can mess with to get both mileage and performance out of my truck. Thanks for any info

Not what you want to hear but those 38s with 4.10 gears aren't doing you any favors in the performance or mileage department.

Yeah I know they don't help to much. I've thought about lowering it back to stock wheels with 33"s or 35"s but that takes some cutting of the front leaf spring mounts that are welded on the frame really good. I'm a welder and they did a good job welding it on. I like that set up like urs looks really good

Oh yeah and I use opti-lube for a fuel additive also.

I get 16 with truck in my sig. The best thing you can do is change tires

Stage one injectors with supporting mods and GOOD tunes.... such as e-fuel, moded HPOP,intercooler, moded IDM, and freshen up the turbo with a good rebuild. Could even think about regearing a little lower to gain factory gearing back

Also look at the simple things such as clean the exhaust back pressue tube, keep filters clean and stay under 65mph! Another thing to look at is the % of torque converter slip and when the TC locks up.

Do you figure in the larger tires into your mpg calculations?

On my truck w/ 35's, I get 16ish mpg uncorrected around town. When I add in the correction factor for the 35's, I'm around 18+mpg in the city.

I got 16 with 35s,3.55 gears,6637, edge evo, and had crappy downpipe. Take lid off the intake and go down tire size

[ratt396]

No I didn't figure that in that slipped my mind so maybe not doing to bad on mpg. And all filters stay clean but I'll hav to ck that exhaust tube

[ratt396]

I should b filling up on fuel today how do I figure in the tire size to get the right mpg? And on the tc lock up does the tunes on the chip control that or do I need to get one of thoses tranny modules?
