Enjoy the low end torque and the consistent power when it's hot out

Any auto guys have delayed 1st to 2nd gear shifts? Seems like it holds the gear about 500 rpm too long. Didn't have this issue with my normal Lund tune.

Oddly enough, I only notice this with the first shift... Driving afterwards I don't notice it. I usually slap it in "S" and force a shift early, running O/R headers with Corsa Extreme's tend to get loud and I don't want any neighbors complaining lol

Also how do you guys keep the gauge from turning off every 5 seconds? I have to keep tapping the screen to keep it from going to sleep mode.

Sorry if its been asked in this 108 page thread already, but do I need to do anything to run E85 on my GT? I read another post where it mentioned needing to use the 47# injectors if I'm running E85. I pass an UGAS that sells the E85 on the way to work every morning, and I'm good with filling the tank with 95 every 3-4 fillups if need be.

Nothing but the flex map , I have 4k miles of straight e85

2011-2014 GT's need to upgrade injectors, 2015+ GT's have just enough to run E85. If you want to run E85 + an after market manifold then you'll need better injectors.

Just loaded my FF tune and very impressed with the Lund tune. Thanks to Beefcake, John, and Greg for fast service! I did read codes after a few runs and it says P0171 and P0174 system running too lean. Has anyone experienced this? Also my afr's don't go anywhere near 10. Lowest I've seen was 12, but that's during some normal driving. At idle it hovers around 14-15. I'm hoping I didn't screw anything up during a few wot pulls. Car seems fine except for those codes.

Did you let it learn the fuel first ?

none of those issues, how long did you wait for the car to learn the fuel? whats the %of e85 on the gauge? how much pump gas was in the car before you filled up?

How do you find out if it has codes ?

Yup, I did normal driving for about 15 mins.

I had about 20 miles left on 91 before I filled up with e85. Not sure of the percentage of e85, where can I find that on the ngauge?

Here's what n gauge reads at idle.
