Just got an OVT Tune

Interesting. I have an RTT on my bed rack that acts as a small parachute.

Are you still on stock tune?

That damn air dam makes that much difference? Hmm

 

I'm on a modified OVT octane learning file, regular fuel.
I doubt the air dam makes that much of a difference, but the tires sure did. I just had my new tire/rim setup on the truck for about a week to try em out before winter, and couldn't break 10.0 with those on.
17" FJ steelies with stock size Cooper Discoverer AT3 4s tires, same tune file same fuel.

 

It's literally a thread about a tune. Then some ppl asked questions, and others chimed in with their opinions.
Then some enterprising entrepreneurs touted their wares. Free market baby!

 

Reddit full of geniuses..
Could have looked at obd2 data and prove the "theory"....

 

I see. For me running premium SFOB on premium fuel made the biggest difference in fuel economy. I am paying more at the pump though, so I guess it’s a wash. It just drives so well on 94, I couldn’t be happier, really.

I went from 265/70/17 C load KO2s at 46 pounds to 255/80/17 E load wildpeaks at 52 pounds and noticed no difference in fuel economy at all. Did notice that I lost some gearing in first and R but I like it better in 6th now, RPMs are a bit lower.

How come you are on regular fuel? These trucks seem to run so much better on 91+.

 

I gave up on running a premium tune file when fuel prices hit the stratosphere.
Also why I went back to a stock tire size and put the chin strap back on.

 

I apologize for the confusion. You would need the Lite bundle from us, so indeed it would be more expensive.
