I installed an S&B setup on my F250 6.7L. It said to keep the battery disconnected for at least 2 hours or you can get a check engine light. To play it safe I waited about 3 hours. Never had an issue.

I sold my 2017 GMC Sierra 6.2L. I pulled my UPR Catch Can setup off before trading it in. 2014-2018 Chevy Silverado GMC Sierra 6.2L UPR Dual valve oil catch can system with Clean side separator, plug in play with billet valves. Can also work with 5.3L with a different throttle body hose. I used this setup with an aftermarket cold air intake system installed. I no no longer need this, sold my truck. Paid about $600 new from UPR. Has drain valve installed onto catch can. Can meet in Hesperia or San Bernardino, CA area or I can ship within the states. I have more photos upon request. I couldn’t include them on this post because of upload size. Asking $425

I have searched countless threads and haven't seen a similar issue. I have a 2017 GMC Sierra SLT 1500 2wd 6.2L. I have had a RC 3.5" Lift in Front and 2" Blocks in Back on 33" Yokohama's. I also have a Hypertech Max Energy 2.0 (p/n 2100), which I used to calibrate my speedo. I installed this setup just over a year ago. Stability Control (Stabiltrac/TC/ABS,etc) has not been an issue until now. My front two tires had strange wear, caused by premature failure of my UCA's. A couple weeks ago i replaced both front tires. The truck still drove great. This last weekend I rotated the tires at home, now the new tires are on the rear. It now feels like I'm driving on marbles/on ice. Not stable at all. the traction control light (on the cluster) flashes on, and I can feel my stabilitrac try to wreck me. It's not an anti-lock deal because my brake pedal acts normal. My Wheel Speed Sensors appear to have slack and are not damaged. I made an appointment today (for tomorrow) to have the two 'older' tires rebalanced. Could that cause these symptoms or am I overlooking something? I've seen others talk about the Rough Country 90009 and the Hypertech 732501 as possbile fixes in their case, but I believe the 732501 is a scaled down version of the 2100. I find it hard to believe its a sensor (Steering Angle, Yaw, etc) because, I would think I would have been having an issue before. This literally started after a tire rotation. thank you, in advance.

I have an 8spd and go with the Mobil One Synthetic LV ATF HP Dex-VI (p/n 124715). This is what is used at the dealers. I like Mobil One products anyway, and I know GM uses Mobil One quite a bit now, so there's a piece of mind of not worrying about a possible warranty concern down the road.

Im looking to do my first oil change on my 2017 6.2L Gmc Sierra. It has 12k miles, bought it two months ago. I usually do Mobil 1 or Castrol with my other vehicles. But since the newer engines have an 8 qt capacity, an "oil change special" at the local parts store won't cut it. Since it is now a $75+ DIY oil change I was considering Mobil 1 Annual performance or extended performance. I drive between 18k-24k miles a year so I'm not interested at doing 3-4 oil changes a year with "regular" synthetic at 7500 mile intervals. I have heard that guys will run amsoil signature series oil for a yearly oil change. Have any of you run Amsoil in these trucks and what kind of success have you had?
