Superchips Cortex 1950 MPG's

[Shooter04]

Just a little info for anyone that's curious. Been keeping track of my MPG's since adjusting for tire size a few months ago. I have it on the Economy setting. I put in 1/4 gallon 2 stroke every tank. My driving habits are conservative....I don't like going fast and usually drive in the right lane going 5 under....yah I'm that guy

After 10 tanks, my total average is 16.4 which I'm more than happy with . With a high of 17.9 (so close to my goal of 18!) and a low of 12.2. These figures are combined highway/city.

For a highway only trip I got 17.6 and city only 12.5

All of these are hand calculated. I add the 2-stroke before I fill up to help it mix.

All in all considering the lift/tire combo, I'm more than happy with 16.4. I expected it to be somewhere between the low 12's and high 14's.

I'm getting better mileage with the Cortex than I did with my TW chip. Say what you want about Superchips, they make a good product

*EDIT*

For anyone that knows, my truck has the 29 gallon tank. Yet twice I've been able to fill it up past that. Once I was able to hit 30.7 gallons. Anyone know why?

Sounds good about the superchip - is that a programmer or chip? I have the Superchips 1705 right now but I don't like the fact I don't have shift on the fly capability. Average 14.8, but when it warms up I have seen 17.5 twice now. Looking at PHP Fu probably to get the shift on the fly and the chance to get tons of different tunes that I can use.

As far as the tank filling, I'm guessing you probably are filling up the filler neck as well. After the pump clicks off I am able to put in another 4-5 gallons.

PHP has some good tuning too. In order, I've run TW, PHP, DI, and now my Cortex. And honestly I like the Cortex the most. It's less jumpy and the throttle isn't nearly as sensitive. Yet still gives power when I need it.

You'll like PHP's though. Bill did great work on my chip.

I got a flashpaq for my 550 2wd and I'm very happy with it. I run heavy tow 95% of the time because I'm always dragging cars around and noticed from an average of 1 mpg loaded improvement which is huge when you're driving 10k+ miles a month. the other day I had to dead head home (empty trailer, which weighs about 7k#) and got better mileage than I got when I first got the truck (stock tune and air intake) on the light tow tune. Once I get my new trans build, or switch to a zf6, I'm gonna go with custom tunes, but for now I couldn't be happier with the superchips. I'm also really happy about what it does to the transmission shifting. My OSS on my tranny is non functional, and uses the genaric shift schedule when in stock tuning. the tuner really helps the shifting when tuned.


another thing. I've had it in the performance tune a couple times without the trailer on while I've been home and holy smoke I was shocked at the power from just the tuner and a DIY intake! Muffler gut and injectors are after I get the tranny situated.
