The additional performance of the 91 Octane tune (was running 87 Octane fuel) is unbelievable. all the throttle delay is gone in my 2006 Dodge Ram 5.7 HEMI and the shift points are very agressive. I just returned to the Economy XS today and am still trying it out but so far it seems great too.. It is kind of a monotonous process to do a retune but I don't blame this on superchips but likely Chrysler.
I was also able to easily recalibrate my speedo for my oversized tires with the tire size options.

I purchased the cortex 3950 for use in my 09 ram with 4.7L engine. The improved shift points and firmness alone are worth the cost of this unit, but you'll get far more than that. The low and mid range have been improved considerably and I've seen an increase of 2.3 mpg highway and 1 mpg city. The truck no longer bogs down on the uphill highway climbs and doesnt frantically search for gears in the city anymore. Most noticeable difference is the increased "grunt" when accelerating from a stop.. I daresay it took my truck from having just enough power to being almost as fun to drive as the hemi.
Later coupled this with a drop in K&N filter and an mbrp catback exhaust and to date ive given a few stock and one lightly modified hemi truck a run for their money.

I wish I would have bought this several years ago. I bought a mid size travel trailer a couple years ago and my truck (2005 Dodge 1500 4.7 L 5 speed auto) would tow it but it was a struggle, I needed more power and better transmission control. I got the Superchips Cortex read the Manuel plugged it in followed the prompts and WOW. It's like a new truck, Added horsepower better solid shifting, it's everything I wanted and more. You can't go wrong with this product. If I ever buy a new truck I'm buying a Superchips tuner the same day.

I have always been on the fence about programmers and how much they can actually improve a vehicle.

For anyone out there that is wondering- after installing this on my 2006 Dodge Ram 1500 with the 4.7 is was 100% worth the price!!!

The improvement in drivability is incredible!!! I've had the program installed (87 octane tune) for three weeks and have towed my large pop up camper and driven rough 1000 miles. I have gained roughly 1.5-2 miles per gallon and all aspects of driving are MUCH better!

I purchased for my Dodge Ram 1500 with 5.7 Hemi. It took a week and three software updates before it would load to my truck. Superchip support was excellent throughout. Unfortunately the device didn't wkrk for me and I returned it. I bought it to improve gas mileage and I didn't see any gain. I read a lot of reviews and this device worked well for some, but not for me. Worth a try.

Put it on my 98 Dakota with the 5.2 engine 5 speed tranny, using the tow/haul mode I can pull mountain hills in the next higher gear than I used before fuel mileage wise I get 13+ towing 2 four wheelers on a trailer in mountainous areas here in PA. Very happy with the extra torque and power.

Everything and more than I expected from Superchips, I'm using the 87 octane tune with the performance trans setting and I can feel the difference.
