2008 Gmc Sierra Performance Chips & Programmers

So you’ve been researching and reading up on ways to get more out of your vehicle, and in an age of ever increasing computer control, this is becoming more and more common of an option. Manufacturers put limitations on the vehicles for reliability, emissions, and future proofing reasons, but, what would it truly be like to push these boundaries? So that you can truly push it to the max or get the kind of fuel efficiency or response from it that you would really like to have? Well let’s take a look at what is available and what it can do for you. There are performance chips, performance programmers, engine management systems, and throttle controllers. It can seem overwhelming to know where to begin. Check out our Performance Programmer Buying Guide.
Not sure which 2008 GMC Sierra Performance Chips & Programmers are right for you? We have over 7429 customer reviews, with an average rating of 4.5, to help you find exactly what you're looking for. Here's what some of our customers have said:

"Intalled easily with juice unit but display unit is a pain to get stuck to dash if you've ever put anything on the dash. There are SOME things it can monitor but you only get to choose between SOME of the things the onboard computer can see. Can't figure out why they wont let you monitor anything the gas version can as well on the diesel. Gas mileage has only increased on freeway and stayed about the same in city. You can definitely feel the difference in mode 3." —Michael L from Syracuse, UT bought an Edge Juice with Attitude CS or CTS for a 2008 GMC Sierra.

"this is second programmer i've owned was happy with last one, mild mileage improvement and better towing power" —Peter S from Mendon, MA bought a Hypertech Max Energy Programmer for a 2008 GMC Sierra, 6.6L Duramax.

"I ordered this to mate with the Edge CS programmer and it does create a nice custom look. The POD was not hard to install, however it is more of a pain for someone with big hands attatching the velcro on the inside with the pod taped to the dash (If you follow the instructions). The POD does have a grey finish and I will eventually need to paint this black to match the factory dash in my 08 Sierra." —Thomas M from Highland, MI bought an Edge Dash Pods for a 2008 GMC Sierra.

"Installed it with a K&N 77 Cold Air Intake and a Jet Power-Flow Mass Air Sensor and saw incredible jumps in power and gas efficiency. Will recomend to everyone, especially with todays gas prices." —Jorge R from Miramar, FL bought a Jet Performance Module for a 2008 GMC Sierra, 5.3L V8.

"this is second programmer i've owned was happy with last one, mild mileage improvement and better towing power" —Peter S from Mendon, MA bought a Hypertech Max Energy Programmer for a 2008 GMC Sierra, 6.6L Duramax.

"Have had this product for a few months now and love it. Have seen a little change in my MPG. You can feel the power behind you when you take off. Would recommend the edge evolution for all trucks. Installation won't take long at all." —Eduardo D from Sugar Land, TX bought an Edge Evolution Programmer for a 2008 GMC Sierra, 5.3L V8.

"I think that the Edge is definitely the next step in programmers. I have used several plug-in chips in the past and the Edge's interface is so much more usable. Different driving styles and needs can be configured and the vehicle optimized. I would like to see more downloadable data from the Edge. I have several upgrades planned, and if the Edge allowed more downloads, then I could compare and contrast each upgrade with the different settings. Otherwise, I really like it." —Stephen W from Nashville, AR bought an Edge Evolution Programmer for a 2008 GMC Sierra, 5.3L V8.

"Best price for the mount and adapter. Easy to install, looks great and does not obstruct your vision." —Edmond B from Harrisville, RI bought an Edge Dash Pods for a 2008 GMC Sierra.

"Ease of installation was real easy and could be done in about 15 minutes - had to call to get the right dash plate for my vehicle, but was promptly sent - free. The correct dash plate was a base grey and interior is the dull black/gray so had to paint to match. No big deal. Programming is simple enough and guides you right through without any problems. Takes just a couple minutes each time you change programs. Have tried each of the performance levels and have since left it on 4 (most aggressive). It definately changes shift points with pretty reasonable gains. Although advertised as up to 40+ hp, for my GMC gains are more like 20-22hp (if you go to their vehicle specific charts, you can see what yours will be). It didn't change my truck to a race car and throw you through the seat, but is a nice upgrade. Most folks seem to see the best fuel improvement at 3, but I'll say that so far on 4 that it also is improving 1-2mpg. I really can't say the true effects for feel and economy yet as I just bought my truck and only has 1,000 miles on it, so it's not even broke in. But if considering, I would say you won't be disappointed." —Dustin A from Garden City, MI bought an Edge Evolution Programmer for a 2008 GMC Sierra.

Check Engine Light On! What Do Those Codes Mean?

It was a chilly night in Montana, but crystal clear. I was standing next to my Honda, taking in the majesty of the great arc of the Milky Way. Using a cool app on my phone, I tracked the International Space Station and saw it fly above my head at 17,000 miles per hour. It’s […] The post Check Engine Light On!
