Just bought a 2015 6.2l

I have been looking for a 2015-2016 GMC Denali with a 6.2, finally found a 2015 GMC Sierra SLT Z71 with almost every option and cocoa dune interior with 30k miles and very clean, at a ford dealer lol. Almost bought another duramax but they either had too many miles or too overpriced for the mileage or year.

First complaint is the headlights, wow they suck, second was the 87 making it knock, I fixed that quick. I am going to try and source a clean used set of 16’ led headlights or maybe some mirimoto hid’s.

Who is a well known efi live tuner for gassers? Truck screams but I’d like to do at least an intake tube to get that big baffle off and get rid of the speed limiter and 4 cylinder shit. Been running M7 to keep it in V8 mode.

Switch out to the new DDM saber, they are bad ass. Do the Morimoto fogs, best you can get imo. Congrats on your new rigg, you will love it. Tow haul should keep it out of 4cyl as well. Happy Thanksgiving buddy...

I just ordered an intake tube to clean up under the hood and a leveling kit with rear blocks, looking at DDM lights and tires now and researching a good tuner.

Hp tuners I’ve been told is the one to use. Get rid of the 4 cyl shit, get rid of power enrichment under 2500rpm add a little timing here and there and I’ve been told these things wail.

I run a Banks tuner on mine and am happy with it. It turns off the cyl. deactivation and is able to bump pressure in the trans. If I need to go faster I have the Hellcat. I tried the cold air intake and could not live with the constant gurgle every time I touched the throttle. Took it off.
You are correct; the headlights suck. Seem to go about 75 yards and cut off. I hate projectors.

I’ve used Blackbear and been very happy with the tuning on LS setups including the 6.2.

Had SoCal Diesel order one from Blackbear and after 7 months I gave up. Seems they weren't interested in my money.

I’ve only dealt with Justin directly and he’s been prompt. Maybe you just got unlucky. Happens.

Do they really work that well? I used to use DDM for years until I had a few issues and switched. Two different brand LED's in mine, and I'm still not even close to happy.

I’ve got Ddm savers and they are pretty good. Had an issue with one of the bulbs and contacted them and started a warranty claim. They have a new bulb on the way. Took a little bit but at least I’m getting a new bulb

First gen was ok. The new ones with no ballast are way better.
