DENALIHD66

Well I'm happy with my Blackbear tune so I guess it'll remain disconnected. Thanks for the info

I was under my truck today and noticed a wiring pin branched out from another harness. It is on the driver's side on the crossmember plate behind the transfer case. It has a plastic placeholder for it, but I can't figure out what this would be for?

That is a Lariat interior, so not high nor low end, but there is nothing ground breaking there... the center screen looks larger and I like they are still using buttons instead of going the Ram route and having all screen (Problems galore). What I don't like is the fact the screen has tons of glare and fingerprints. While I think the GM interiors could use a bit of an update, has anyone actually sat in one or driven one? The layout is well more thought out than you think. Yes, the Ram interiors look amazing, but the overall functionality for a TRUCK is better found in the GM models. Large buttons, everything is easy to get to, and durable. The Ram does have some cheap chintzy components that would not stand up to the real world for anyone using them like a real truck. Speak of the devil, just moments later, look what I found: https://news.pickuptrucks.com/2020/04/2019-2020-ram-1500-2500-3500-multimedia-display-recall-alert.html

From factory mine's recommended 93. Doing lots of research, there is a higher concentration of detergents in 93, and it burns cleaner. I've never put a drop of anything else in it, so I'm not sure for comparison sake, but the engine/power have never been an issue. Just having cleaned my throttle body, it looked like there was less than 5k miles of wear on it. Virtually no carbon buildup at all.

Care to elaborate? Truck also had the same transmission problems with the oem intake.

So, if you read my post, you'd notice that I also got it tuned. Also being the driver of my truck, I can tell you that even with my larger and heavier tires, it runs faster than my truck did stock. I am not incorrect in my statement of extra HP. Cold air intake alone added more than 10HP. Don't bore us with your ignorant opinions.

I did K&N CAI, Borla ATAK catback, and Blackbear Tune on my 6.2.... 93 Octane. If I were to drive a stock 6.2 now, I'd probably be super disappointed. My bolt ons and tune probably added about 40HP.. maybe more? Also no more AFM makes the truck more compliant. I also have gotten slightly better MPG since removing it as well.

I am under the same impression. It basically just looked like a ported throttle body.

I saw online today Jet Performance makes a performance throttle body. It has updated programming in it, plus the opening is grooved for improved airflow. Is this the one you were looking at or is there something else?

I have a 2015 with 8 speed and have had issues with it since the first month. Very hard shifts 1-2 and 2-3 on cold starts (100%) of the time. Also weird shifts on in-between gears, etc. Basically everything that everyone else is complaining about with these. I got a blackbear tune done, and that helped minimize some of the annoyances with it. One thing remained, the clunky shifts 1-2 and 2-3 on 100% of cold starts. Yesterday I took apart the cold air intake, MAF, and throttle body. Cleaned everything all up. (First TB cleaning and it wasn't that bad after 51k miles). Put everything back together. It took a couple of cranks to get it to start, the first 2 cranks it stalled out. 3rd attempt it fired up and idled fine. When coasting down my hill, I noticed the 1-2 shift was smooth and quick as silk. The whole drive thereafter the shifting was absolutely perfect, and this was right after it sat (cold start mind you). One odd thing was that my cruise control wasn't working. After getting to my destination, I shut engine off, waited a minute, cranked it back up. Same thing kept happening, it would fire up then stall out within seconds. I had to rev the engine in order for it to stay on. Long story short, I figured out I mounted the MAF sensor in backwards by accident, so I flipped it around. Truck fired up fine, but then the harsh 1-2 shifts etc returned. I am wondering if I am onto something as far as the MAF and how it shifts during a cold start? I believe there is also a TSB notice about excessive casting when the MAF was manufactured, and it relates to hard shifts after a cold start. I'm currently searching online to find it, with no luck so far. Was wondering if anyone would chime in and let me know what they think. Would replacing the MAF be beneficial? I cleaned the crap out of it when I had everything apart. Edit: Found a thread started with no responses. Not sure exactly what part to inspect? Is this the OEM air intake or does it refer to the MAF that carries over to be used in a Cold air intake? PIP5446

Glad to hear you like the BDS. The 4" system is better for me overall and I want some more rubber all around. What size tires did you go with? It looks like you had to trim the front air dam (Which I usually remove anyway). Do the BDS 4" and 6" systems increase off road flex at all? I'm thinking because the shocks are fixed it retains the same flex but bigger tires help just a tad for obstacles.

I like to keep the factory 20s. In my opinion factory wheels look great on these trucks with a little added rubber. Typically if you go offset, more trimming is required because of more tire turning arc (negative offset). These trucks are typically +27 OEM wheels.

Dang only 2 sizes up and that much trimming? Do the wheel well tapers (non-rounded) really cut down that sharp? I went from 275/55/20 to 295/55/20 with 1.8" Bilstein on my '15 and it has plenty of clearance. It does rub on the sway bar at full lock moving forward though.

Looking to get a few questions answered because it still seems like there isn't a ton out there mod wise for the Denalis with the ARC shocks. 1. What's the largest tire you can run without any suspension mods? Stocks are 275/60/20. Would it fit up to 295/60/20? Is it just me or do the Denali's look like they have less clearance in the wheel wells than the other trimmed trucks? 2. Rough Country has a 2" lower strut spacer. Would that negatively affect the suspension travel for light off road use? Can you add a larger rear block (+1") without having to add shock extensions? 3. I've done as much research as I could find on the ARC shocks... are they legit/worth it? 4. In your opinion, which would be a better overall vehicle (assuming some off roading as well) in terms of ride quality and performance? A Denali with the BDS 4" lift kit or AT4 with the 2.5" BDS Fox 2.5 Coilover setup

The biggest change they need to make is to offer an extended range fuel tank. 24 gallons across the board is pathetic. Especially for those towing and using their trucks for off roading. A selectable auto-locker would be nice. GM uses the Eaton automatic locker, Ford and Ram use Electric lockers. Why not make an option that is selectable: Open diff, auto lock (activates when wheel slip occurs and automatically disconnects), and a mode that keeps it locked. (Basically the same concept as the 4WD/Auto). Interior is not as bad as people are saying. Maybe a few tweaks but nothing major. How about showing the driver what gear the truck is operating in, and what cylinder mode? A discount for choosing "Standard tailgate" as an option versus the "Included" multi Pro tailgate on the GMC's.
