Gen 2 Gas Millage

[Wfo]

I’m at 7500 miles with Cobb stage one. Getting 14.4 mpg. Lots of highway driving 75/80mph

Creeping up to 15/15.5 mph without cold staring and 40-55 degree weather. We’ll see how much better it gets in the 60s and 70s .
Mostly running 89 octane

I forgot to add that I remote start my truck, it idols for 10/15 minutes each start in the cold weather.

There's another thread on here about how to get into Engineering Test Mode, and then you can adjust the 'ratio' the computer uses to calculate Average Fuel Economy (AFE). I did it to mine after a couple of tanksful to get a good diea of what ot program in, and now my dash AFE is within about 0.25 MPG or so of the hand calculated value. I've posted the how-to in that thread, you should be able to find it with the search function and using AFE as the search term. Let me know if you can't find it and I'll try to track it down. Been a while since it's been discussed.

I think it has been posted a few times, but here is a link to one description of how to do it.

Also, the results of my adjustments in ETM are there. Now my Indicated MPG and my calculated MPG are typically within 0.2 or less of each other.

T!

yeah, that's the link to what I posted earlier. Had some trouble getting my '17 into Test Mode, but it finally worked one day. Here's the information on how to calculate the AFE Bias number to update you computer, and a discussion on getting into ETM:

Here's a link in the Forscan discussion with a video so you can see what the process looks like:

Good luck, let us know how it works out for you.

If you can afford a Raptor you shouldn't be worrying about fuel cost. Just drive it on premium like they suggest and have a good time, otherwise trade it in on a YUGO
