So last night I installed the Superchips 3875 on my 08' JK and all I can say is AWESOME!!! I played around with it on the 93 setting but didn't have all of the 91 out so there was some pinging but after resetting to 91 it was GREAT!
Can't wait to get this 93 ran through to bump it up.

All around as far as shift points and just drivability it's 100% better. No gear hopping or need to turn OD off while on the highway with the tire size corrected. Even my favorite S curve on ramp that I used to have to crawl through because the Jeep always though I was rolling and ABS kicked on flowed smoothly.

THE BEST PART... 23.5 MPG!!!!

 

So installing a super chip stops that ABS crap too? If so I gotta have one

 

Nice, I just ordered one too. I have an 07'.

Do you have gears installed?

 

Not sure if it stops the ABS but it helped this morning!!!

Gears are the stock gears but there are adjustments for just about all of the lower gears.

 

So just getting this SuperChip will increase my MPG even if I stick with regular octane or do I need to switch to premium?

 

I got mine Labor Day weekend. Put it on the crawl feature... AWESOME! Then back to 91 octane. No more slight uphill, grab a gear, rev to 5,000rpm to merge on freeway! Will hold 60-70mph in overdrive. I LOVE IT!!! And it's $300

 

Not sure? It has setting for better MPG but I wanted the added power and torque...

Again VERY HAPPY with it so far!

 

Those with 6 speeds you noticing much?

Thinking about getting the trail dash...

 

Wondering the same thing, ive got an 08 6spd

 

6 speed here and I love it. I'm using the 87 octane tune and it's been great (along with the crawl tune on the trails).
