Oil recommendation after DOD delete
Why not go with 0W-40 that GM is now saying needs to be used in the newer 21+ engines? After my warranty ran out I used 5W-30 for a few years then this year switched to 0W-40 and have the best oil pressure I’ve ever had…and it’s more consistent too….doesn’t fluctuate as much especially at a...- BMPNUGLS

Converting my Air Ride to Regular Suspension?
You might look into Arnott shocks/struts - for my 16 Denali XL they make passive replacements (with built in resistors to fool the system) which gets rid of the magneride yet keeps the self leveling air system in the rear. I went with these all the way around and couldn’t be happier! I swear...- BMPNUGLS

New oil change price at dealer!
Is that the new weight requirement (0W-40) oil?? Around here, and a lot of places online, finding 0W-40 full synthetic in stock is becoming a challenge due to this issue. Personally I run the Pennzoil Ultra Platinum 0W-40 but can only find it on Amazon….when it’s in stock and the price isn’t...- BMPNUGLS

Help with AC
My first thought is you may have a clogged expansion valve….if your compressor is engaging and low side pressure goes up WAY to high..with relatively no high side pressure change. Or a plugged condenser. -
Tuning other than black bear.
I have a Diablo Intune I3 Platinum for my 16 Denali XL and could not be happier. Diablew also has options for custom tuning as well - similar to the black bear method. The Intune I3 has some custom tuning ability that I love playing around with - it’s amazing the affect some parameters have...- BMPNUGLS

Arnott MR4262 for replacing front Magneride Z95 suspension info
Yes the rear passive shocks have air - so they retain the ride height adjustment same as factory. And the passive Arnott’s have a resistor built in with a factory style wire harness that bypasses the magnaride all the way around - so they are plug and play! Best upgrade/repair I’ve made to my...- BMPNUGLS

Arnott AS-3429 Failure
How in the world can that happen!!?…the threads on the shaft tips don’t look damaged from what I can tell…so unless there was a lot of rotation of the base during install for some reason idk how that could even happen….- BMPNUGLS

Arnott MR4262 for replacing front Magneride Z95 suspension info
I replaced the struts and rear shocks with passive Arnott’s all the way around a year and a half ago (37K miles on them now) and they are holding up great and truck rides better than it ever did new! The front Arnott struts do have larger springs than OEM…especially on the XL version from what...- BMPNUGLS

At 125K miles the struts gave up on my 2018 Yukon Denali
At 140K miles my front struts locked up SOLID on my 2016 Denali XL. Replaced both front struts and rear air shocks with passive Arnott’s (to remove the auto ride) and could not believe the improved ride! I swear it now rides better than it ever did since I bought it brand new! Now at 177K and...- BMPNUGLS

What are the best AFM delete tune/plug in devices?
On my 16 Denali XL I used a Range AFM disabler from day one until the warranty ran out…then sold it and bought a Diablo Intune I3 to disable the AFM and tweak the ECM & TCM tunes - couldn’t be more happy! With the 89 octane tune with tweaked throttle response (maxed at 20%) and firm shift tune...- BMPNUGLS

Larger tires on 2025 AT4 Ultimate
If you go to https://www.customwheeloffset.com and put in your vehicle or search their site for fitment….but better yet you can see their ‘customer builds’ where people have installed oversized wheels/tires and submitted pictures along with details of any suspension mods / thrumming needed if... -
OIL PSI / BRAND / WEIGHT
Before trying any ‘home brew’ flush or additive to the oil I would use the new Valvoline Restore & Protect oil for 3-4 oil changes. Do some investigating, but it’s got a ton of real world results cleaning up the internals of the engine…and I’m on my 4th oil change with it and the engine seems...- BMPNUGLS

Transmission Cooler Line Popped Out/Update
I’m betting a trans cooler port in the radiator still had a plastic cover or plug in the new radiator that wasn’t removed….which could be why your line popped off as well….it built up pressure and blew off. My first thought would be to check trans cooler fittings and make sure there is no...- BMPNUGLS

Help with Rims (No more 24s)
I have a 16 Denali XL that came with factory 22’s and I hung on to them until the 100K mile mark and then switched them out for a set of 20’s w 275/60/20’s and the improvement in ride was unbelievable!! I’d go as far as to say the increased sidewall was more of an improvement than when I... -
New Arnott magrides are very stiff/bouncy
I installed the same struts last fall and love the ride….and they have seemed to get ‘softer’ the more miles I put on them. Immediately after the install my front was raised as well…almost leveled the front with the rear. It took a few thousand miles but the springs eventually ‘settled’ and...- BMPNUGLS
