installed quickly and is straight forward. installed on a stock xterra mileage went up a bit and there was for sure a snap to its go. then put a k&n intake in and that helped even more. overall both great products

I wish I had this cortex long ago!! Honestly maybe a couple of mpg's on xs 87 , but one switch to 93 octane & advance timing& full throttle restriction off, Hold On!! Cause your 5.6 ltr v8 becomes a BEAST! Open box ,register online,plug it in follow inst. about 20 min or less. Thanks Autoanthing.com&Superchips

I had a little trouble with installation. Super chips had write special codes for my truck. The turn around time was amazing and my truck has never run better

Before I got this chip I thought my truck was mean. And it was. Had k&n put on and exhaust and it would run. Or so I thought. I hooked this up and it woke my engine up. Have to feather foot it or risk melting my tires, which is all terrain grips. Love it. Just ready now to find a good long stretch to really test it out.

This programmer works great im pushing 400 hp now. And at the same time im getting better gas milage than ever. Last week on milage xs mode i got 16 mpg city which for anybody who has a titan knows its hard to even get that on a long trip could be happier

I was getting 17.1 with my 2008 frontier. After using the cortex to set to 87 octane my mileage went down to 13.5 mpg. After 4 tanks of gas with highway driving it only increased to 14.1. I switched to economy mode and the mileage styed at 14.1 and never improved. After resetting it to factory specs the mileage increased to 16.1 immediately. I bought the cortex for towing occasionally and being able to reset chasis codes. This was the largest waste of money unfortunately I used it for more then the 30 day refund policy so I am stuck with a $350 code reader.

I put this tuner in my '09 Frontier and it really has made a difference. Once I installed the updates and figured out how to tune it, I ran the 91 perf tune and the gains are impressive. Like most others, I have actually gotten better gas mileage from the 91 perf rather than the xs fuel saver tune. Great product!

The installation was extremely quick and directions were easy to follow. I did notice gains in power and response related to passing power. Not as good as I hoped for 0-60 acceleration. Overall a decent upgrade for the price
