My replacement unit came in and its installed. So far it works perfectly. Throttle sensitivity adjustments DO work on the fly and make a dramatic difference in pedal feel. As long as everything keeps working as advertised this will be a great product. And BTW... Range answers the phone every time I call and they are more than willing to help. -Eli

Just because you have Bose and the big screen does NOT mean you have NAV. It is a separate option. However, if you do have those items your unit can be upgraded to NAV at the dealership via software. -Eli

Here are a couple small editions I made to the AT4. I swapped the gloss black mirror caps for some dark sky caps. I also installed the GMC logo puddle lights. I like the look. -Eli

I tried to install mine this morning. As soon as I turn the ignition on I get reduced engine power, ESC and parking brake errors. Range is sending out another one. Bummer. -Eli

Updates?

Reverse flow (comma) turbo. The engine is reverse flow with a “hot V” turbo setup. The intake is where the exhaust normally is and vice versa. Provides better packaging and a much shorter exhaust path to “both” sides of the TWIN SCROLL turbo. ? the lesson here is that when you troll the internet looking to correct someone you don’t always know what they were originally saying. Maybe they left out punctuation for short hand internet talk? It’s very easy for the teacher to become the student.

I have run them in the snow. They perform pretty well.

275/70R18 Milestar Patagonia. 33x11 mounted on the truck at 40 PSI. Stock Suspension.

Mine says the same.

It's not even about the money to me. It's an added bonus that they are very affordable. I don't mind paying for a tire that does everything I want it to do. I have yet to find a tire this aggressive that does everything as well as this one does at any price. It's not perfect in any one area but it does most things well without much compromise. -Eli

Like the title says, what pressure are you guys running when you switch out to Load Range E tires? -Eli

They are. milestar Patagonia MTs. I had a set on my JL Wrangler that I put 20K on. They work excellent off road and they are the best driving and riding MTs I have ever had. I have run approximately 15 different MT and AT tires from most of the big manufacturers.

I didn't go with the "biggest" that would fit but here are 275/70R18 Milestar Patagonias. -Eli

Figured I would update this for anyone searching keywords. Just had 275/70 R18s installed. They measure 33" mounted on the truck. They are quieter and stronger than the Duratracs. I have had these in the past so I knew what to expect. Search reviews on them if you are wondering.

I have had these on other vehicles and they were great and quiet. I am thinking about putting a set on my truck. Is anyone else running them? -Eli

Those are aluminum.

Its not in Sport mode if the flag isnt there. When you turn the dial to "check" the mode it switches. Every time you touch the dial it changes a mode. Normal mode is enabled every time the truck is started unless you are in Tow Haul and restart within 2 hours. (I think its 2 hours) -Eli

I have one on order. I'll post results. -Eli

Its for the intake only. -Eli

Mine may have come back after not driving the truck for 3 days.

I have searched and read. I have a pretty specific question. What tire size will fit with NO rubbing and NO modification on a stock height AT4 on the stock 18s? I am looking at Toyo MTs. 285/70? 285/75? 295/70? Or just stick with 275/70? Also, pics of stock height AT4s on OEM 18s with plus sized tires would be great. -Eli

Range still lists this as not compatible with the 6.2L/10 speed. I ordered one and did my own testing. I waited until I could repeat some results before I shared my findings. I have a '20 AT4 6.2L. The Range unit DOES work on my truck. I did have the slight RPM surge under part throttle in a high gear that others have reported. I believe this is the reason they are saying they are not compatible yet. Here is my theory and what I have found..... This surging only occurs between 8th and 9th or 9th and 10th gear. It appears the computer is trying to decide which gear to be in under the current operating conditions. If I put approximately 100 miles on the truck with the unit plugged in the surging totally disappears. If I unplug it for a while and then plug it back in, the surging comes back. I believe this is nothing more than the TCM having to "learn" what to do with DFM disabled. I greatly prefer the way the truck drives and sounds with DFM and auto start/stop disabled. I would be interested to hear from those of you that have had the surging issue. Drive it for 100 miles and let the TCM learn. Let me know your results. -Eli

My DFM is disabled. I don't have exhaust flappers or loose heat shields. Again, this noise could be completely normal I would just like to know what the heck it is.

Which is a huge red flag in my mind for CV angles. Even though they look fine.
