I have a 2015 Denali 6.0. on the performance tune it shifts better and gave it more get up and go. It didn't affect my mileage either way.

I got one for my 2005 Chevrolet Silverado and I love it. I originally got it to correct the my speedometer and shift points for the larger tires I put on, but I now use it to read and clear dtcs, increase mpgs or performance based on tune, and even for monitoring certain readings. If you want something based on pure performance you may want a blackbear ecu tune. But for versatility and on the go changes, this can't be beat.

we have a 2008 3/4 ton chevy and are not having any luck loading this, keeping getting a different code, even tho the local chevy shop says they set it to factory performance. Good luck.

I use it on a 04 Tahoe w/ 5.3.... I run the performance program most of the time because it seems to have the best mileage and performance overall.. I did run the mileage program recently on a 800 mile trip and I got about 2 mpg better than the Performance program, but the responsiveness was definitely not there. for any type of towing use the tow setting.. I've tried towing even a light trailer with a couple of quads and I get a check engine light.. When you scan for codes it shows a lean fuel code for whatever reason.. Never had that happen with the Tow program..

this worked on my snow blower, it installs fast, works great, but would recommend you change your fuel lines & clean out your fuel tank, & use a non ethanol gas or use a good gas stabilizer.

I've had it on my 2014 Sierra 1500 Z-71 for 4 months. The kit is good quality. Depending on your suspension, this may actually bring the truck front up a little too high. I went up an inch in the back to compensate (replaced the stock one inch blocks with two inch).

Hey if I turn my my performance all the way up. Will I need other upgraded parts like thermostats and does it work for all gas gmc

Yes this will make your truck run like a bat outta hell with that setup! The ts chip is one of the best on the 7.3 I have the same setup on my truck and it runs awesome.

I install this unit on a 2002 f-150 standard cab. I mounted the module to the underside of the bed , I was concerned about the weather so after all the hook ups I covered the module with weather proof putty. you can pick it up at any RV sales.I tapped into the reverse backup light on the rear right taillight assy .Mounted the sensor on top of steering wheel and ran the wire to the rear of truck and connected it to module.So far all is well

on fuel economy mode no change in mpg (same) i run now 87 performance what a power diference lower end gets a lot of kick ,it realy shows serious power on 93 performance but i dont want to run 93 because of $ per gal so you'll be happy with 87,i got that unit just for towing i tow 6 k boat than it burns less fuel and pulls way better up hill here in new england would highly recommend cortex (only) nothing else ,my last truck dodge ram with flushpeg waist of money no change in power stay away cortex kicks a.. Buy it and enjoy it

if there is a better chip, I'm not aware of it . I have a 2500hd with a 6.0 L gas motor, K&N air box and filter. I programmed the chip for Towing. It definitely added Throttle response. But I can't say Ive noticed any mileage improvements. With the performance enhancements I think I drive the Truck a little harder. Also the chip requires premium fuel. Bottom Line if your trying to save money on fuel you'll probably be disappointed.

I have 11 gmc sierra crew cab it fits fine. The denali is the upper trim package, so yes it will fit. When I installed mine I removed old lens first, put a bead of silicone around where old light meets body, common leak area and then installed cover, works fine.

You could check the manufacturers website. It worked well on my 2007 avalanche. Only issue was I couldn't get it to pass emissions after installing. Had to disconnect and get the dealer to reset.

I installed it on my 2000 Gmc Sierra 2500 4x4, in one weekend, only problems i had were my manual 4x4 shifter linkage, and gap guards. the linkage requires welding. and the gap guards aren't just only for looks like i originally thought, they prevent the engine from running cooler which can mess with the internal AC/ and heater. but other then that the kits great works great and looks great

Probably. I have a 2007 denali so that is where my research was. You can look at arnott.com for more information.

Mine works great. I think you will really like it. I love mine. Particularly with the snow this past winter. There is some trial and error involved in installation but not too bad.

I have a 03 gmc sierra and it worked for me main reason I bought was because I converted all my taillight bulbs to led and it no longer hyper flashes with no other mod other than this every thing on my truck still works as it should no problems

Might be perfect as these VM's are actually two stroke snowmobile carbs. Check for cfm and inlet size.

Yeah I just bought this for my brother for Christmas. He has a 2007 5.3 sierra 1500. This is a awesome product. You should expect about 30 hp and 2 mpg more than stock. Main difference is in the transmission shift points it keep pulling through the gears. Unlike stock where the shifts are really smooth and you feel like your losing power. Also there are a ton of extra gauges and features to help track your trucks performance.
