Product Information

Product Description

2011-2016 CHEVY / GMC DURAMAX 

Includes 4 week Tuning support pack! 

LIFETIME SUPPORT PACKAGE
This recommended upgrade offers unlimited flashes and basic tune revisions on ALL TUNES. You’ll receive automatic tune updates so that you can take advantage of the progress that we make and enjoy the timelessness of the EZ LYNK AutoAgent 3.

SOTF SWITCH
This upgrade is needed to correctly run SOTF (switch on the fly) tunes. Without the switch installed, your tune will default to the lowest power level. Installing the switch will allow you to adjust power levels and maximize your vehicle’s performance instantly.

TCM TUNING
This HIGHLY recommended upgrade will increase the line pressure in your transmission so it can keep up with all the added power your engine will be producing from the tunes. We highly recommend TCM tuning to anyone that plans on running anything more than a tow tune. Please specify if you have any transmission modifications when ordering TCM Tuning.

    Exhaust came in on Tuesday. Well packaged and perfect box. Got the truck completely done today. Slow day at the shop so I got it all done. I want expecting that much power honestly. What a difference. Already 3.5mpg better. Truck is a monster now. Shocked really. Sounds sick too!!!! Thank you guys for the product, communication. Perfect. It's like a new truck.

    5 stars Fast shipping, quick response to my email, excellent products. Tune loaded quickly with no issues and shifting is smooth with the tow tune but I'm still experimenting. I needed a exhaust that wasn't to noisy and yours a worked perfectly and no leaks from the clamps. I did remove the 4 inches from section of straight pipe to fit my long bed crew cab but that seems to be the norm so the same pipe will fit the long bed mega cab. You were a word of mouth recommendation and I'm glad I remembered the name of your company. Thank you for helping me bring my truck back to life.

    Installation for exhaust was pretty straightforward. Internet connection is slow where I live, so download of the tune was pretty time consuming. Also had to take off my dashboard to access unlock location for ECU. On the upside, easily added 3mpg - sometimes a little better when taking it easy. Amazing to get almost 30mpg (sometimes low 30's) out of a 1/2 ton pickup truck.

    I like it, the install wasn't too bad. Wish it would've came with instructions, that would make it a lot better.

    Marcus

    Moore

    Everything I needed was in the kit I was very happy with Everything except the shift on the fly selector. I spent 2 hours installing it in a very inconspicuous location. After I installed it we could not get the proper voltage reading for it to work correctly with my truck. So now I have it still mounted in my truck but I had to unhook it so it was a $150 item that I won't be able to use. But everything else worked very well and I am pleased with the outcome of the installation. Thank you for your products. Will be purchasing more form your company in the future

    Bobby

    Holt

    Instructions would be awesome. But overall very happy with products performance

    Kyle

    Roose

    Product was not really compatible with the C/C as turbo is smaller so GDP will only give me 1 tune. I understand why but, I bought the 5 position switch was so I could adjust power as at times I do not tow and others 30k lbs. Other than that like the tune and GDP tech line was very, very helpful So can't use the 5 position switch but will keep until I install a larger turbo as per GDP. Thanks for the product and it really sounds like a truck now.

    Bill

    King

    Everything went well. Took me 4 hours to complete, solo. Only gripe I could have (which I don't) would be the lack of instructions for the bracket that bolts to the exhaust. Took me a while to figure that out as the instructions showed a different set up. Preciate the kit. Have recommended to other folks.
