Superchips?
I just got my first Jeep.
An 08 Rubicon Unlimited with Fabtech 5 inch lift on 37s. I just instilled a superchips and AEM intake. For the people who has the superchips in their jeep. What setting are you run on the superchips to get better MPG or what setting should I run to get the best performance and MPG?
Thanks

I would use 87 octane. There are people running 93 octane but I personally would stay away from it due to the heat from the gas igniting and the rings are made for 87 octane. I use 87 octane and I am very happy with it. Just my

Yes I am running 87 octane. The milage with stock 4.10's and an auto is about 15-16 on the highway. Are you running stock gears? If so You might want to think about regearing with those 37's. I know I am and I'm on 35's. Oh are you an atuo or stick?

It is an auto. I have 5.38 gears and right now my MPG is 13.3 in the city with 91 octane tune and 91 tune. I have not done a lot of freeway driving but I hoping to see 16 or 17 MPG on the freeway at 65-70 MPH.

i change the setting every once in a while and have not run across one that offers much noticeable MPG over another. so i usually opt out for a little extra power with the 91 tune. drop the cooling fan temps, put in royal purple oil, and 50/50 coolant w/ royal purple additive; and there will be no excessive engine heat.

Personally, I run a 180 degree thermostat in the summer, and swap it in when the hard top goes into summer storage. I check the thermostat on the stove in a pot of water to make sure it opens at the temperature setting as it should (making sure the wife is away as cooking auto parts is strictly verboten in my household) and then install it and shelve the one removed.
With the warmer weather I'm still reaching proper operating temperature, I'm just beginning the cooling process earlier.
