Check this out... best gas mileage I've seen yet...

When I got the truck back, I immediately installed a PPE tune.

I've been averaging 13-15mpg in mixed driving. That's not babying it but it's not beating the crap out of it neither...

I sold the PPE and installed a Diablo T1000 Trinity tuner.

It only adds about 120HP and 240 ft. lbs of torque to the existing 300/520

Granted, it's only been two days but I've driven it enough to know what it's been doing.

Here's what I'm averaging the last two days... still running 75 on the highway and driving normal around town. (50/50 mix)



I'm having to send the Diablo back because I can't adjust for gears or tire size but hopefully the new tuner will get me the same results.

Hi Mark, that is some great numbers!! Are both tuners having a problem with setting gears and tire size?

No, the PPE was adjustable and I could remove the ABS and BRAKE light by setting the correct numbers.

The Diablo has NO ability to do so.

Yesterday I ordered this EDGE unit...




It has 7 levels of tuning from a towing setting to up to 180 additional HP and 385+ ft. lbs. of torque.

I drove the truck yesterday in the city all day... no highway at all and averaged over 18 mpg.

It seemed if I stepped on the gas harder than normal, it would drop the average down a bit but it always pulled it back up to the 18-19 mark.

Apparently with the 24 mpg, I did more highway driving than I thought but in all fairness, I spent a lot of time yesterday with my truck idling while I ran inside here and there to take care of business.

I see I'm going to have to replace rear tires. If I just try to merge from traffic out of my shop's driveway, I'll leave more rubber on the ground than on the tires. Definitely going to have to curb that action...

So how does these tuners work to achieve the MPG? Little skeptical on the significant MPG increase and just want to know what the concept is to make a vehicle that gets 10-12MPG average to 24MPG...
