I've been seriously thinking about this as my next upgrade. I was going to do a MBRP cat back next, to compliment my CAI. However, I'm starting to think that I'd be better off getting this next and then the exhaust later. It seems like I'll see more of a gain with this than the exhaust. And then when I get the exhaust later it'll all work well together...

 

So has anybody using this been able to get lockers in 4Hi?

 

I'm able to lock up in 2 hi. I've never tried it in 4 hi yet.

 

The coolest thing about the SC is that you don't have to wait for an option to come available. Everytime a new option is ready all you have to do is plug it into your computer and download it. Your SC will never be outdated!

 

Thanks! Seems like if it works in 2wd it should work in 4hi.

 

Hi Calypso,

Thanks for the post.

I was already aware that the upgrades were via download. My only point is that I'd rather use my mod money on something else until those options become availabe.

Thanks

Jeff

 

Definately saw a mileage improvement on my vacation to Colorado. Drove 1620 miles in 6 days, and the worst tank (hand averaged), was 17.7. Best tank of the trip was 19.4, which surprisingly was the trip up, uphill the whole way. Had a hell of a head wind coming back down to Carlsbad, knocked it back to 18.8. Elevation in Carlsbad is 3100 ft, and in Florrisant, CO is 9600. Made it as high as 10,200 ft or so. My last trip to Cloudcroft, NM was the first weekend of the month, 280 miles total, and the average was 16.4, the highest elevation is 9300 ft there. Both trip had lots of slow dirt road driving as well as 75+mph highway. The biggest difference was weight. The short trip to Cloudcroft was just me and my golf clubs, the trip to CO was with 4 people in the Jeep, 5 days of luggage, 2 sets of clubs, and a hitch-haul rack totaling about 250 pounds. The ass-end was sqauted 2-3 inches under the weight!!!

The tranny definately shifts better, and the throttle is more responsive. It doesn't hunt for gears as it did before, and by using GPS, the speedometer and odometer are dead on now. As for power, I only used the 87Perf tune, and did not notice much, but the other features have help a good bit I'd say.

 

Yeah I can lock the rear in 2 hi. I just ran out and did some squirreling around to double check. I think what I've heard people complain about is that you can only lock the front or rear but not both at the same time with the superchips. And when you run the programer it gives a warning about not going over 30mph locked but I don't know if it auto unlocks if you go over 30mph

 

anyone try the 87 tune then try the econ mode? I am not getting any better milage on the 87 tune than stock and I have a 1200 mile trip coming up so I am debating running the econ mode for it.

 

I don't get any better economy either - that is not what I expect. It gives better performance and features - at the same mileage for me so it's a big winner. I have done the 87 tune and got the same MPG. I'm doing the 93 tune and seeing what it does - but it doesn't seem to give better performance than 87. I haven't used the econ programming but I will play with that and tow mode soon.
