if you want to sell it let me know haha...maybe its something isolated to your truck? 

weird that some are ok and others arent. 

PM me an offer and I'll think about it. I haven't decided what I'm going to do with it yet besides unplugging it.

Well OnStar still sees it and I have an extended warranty that I'm not risking. Plus the transmission is shifting harder at low speeds. I cannot recommend the Range AFM for a 2016 GMC Sierra SLT with a 5.3 and 8 speed.

Have you contacted range for an update? I read somewhere that they fixed the issue with an update so onstar can’t see it anymore. I had the same problem with mine. I sold it because I got the vehicle tuned.

I just got it back from a supposed update to remedy this problem, OnStar ran a day ago, a week after I got it back, and the diagnostic report was blocked by a device in the OBD port. Range replied today with oh well unplug it when OnStar runs the diagnostic test, like we know when that will occur.

Oh ok. I wouldn’t worry too much about it. If they ever question a warranty claim due to OBD port usage just tell them you had your insurance company dongle plugged in. But from what I gather with any major warranty claim they look for index markings on ecm. If they don’t match up with what’s in there system per the updates they did on your car at any dealer then there is a problem. Since range leaves no marks you will be fine. This is the way I understand it.

Funny thing is my truck shifts better without it, I had the transmission fluid changed recently and the truck rides sooo much smoother.

it seems there are a decent amount of stories like this as well. Really has me going back and forth on getting one lol. 

Is it worth just accepting the helicopter sound with an exhaust to not run one lol.

I have the 6L80 and did not notice a difference when I had it. I recently changed out the oil to AMSOIL and noticed a smoother transmission mostly when going from park to reverse or drive. No more clunking. Smooth and quiet.

? Yeah you have any solid data backing that up or just the words of a few AFM haters on the forums? How prematurely? 50k? 75k? 100k? Would be nice if you can let us know when! There is nothing anywhere that points to running V4 mode causing failures, GM would have pulled that in a heart beat if it was going to cause a bunch of wasted money in warranty claims or recalls. GM has a history of long lasting reliable engines going well past 100's of thousands of miles, we have had multiple at our house and a few friends I am close with (one pushed 300k before trade in with zero issues). You can't believe everything you hear on the internet and it doesn't help to pass on false info...

LOL LOL LOL You sound like my dealership when i tell them all the issues that these trucks have are all documented on the internet all over the world. They say you cant believe everything you hear on the internet. LOL that`s what they teach the techs at the training seminars. Unbelievable

      Injector update

      By iso221 · Posted

      Because single shot injectors are ancient and multi hole injectors provide smoother running engines and sharper throttle response due to the fuel being atomized better..the best lead I have is a 24lb blue top injector almost everything matches up but the injector will put out about 26lb/hr which is just outside the gm threshold.figured id ask here to see if there was an absolute answer

      Injector update

      By CamGTP · Posted

      Why is my question?   Any change in injectors requires a tune. Unless you are going back with the OEM part number or a newer part number of that same injector.   Any size difference or type difference like the EV6 style injectors all have different injector data for them. And there is no EV6 injector that matches the factory 25 lb/hr size that your truck comes with. I've been messing with these trucks and tuning them for a long time and what you trying to do doesn't exactly make sense to me.

      When a condition becomes a business model.    https://www.gm-trucks.com/gm-truck-suv-incentives-pricing-2026/   Zane posted this in "Latest Articles".    The honest bottom line   Truck buyers have spent three years assuming this is a temporary condition that will break once inventories normalize. GM just presented it to investors as a durable strategy, on a chart, as evidence of good management.   Inventory did normalize. GM is at 511,000 units and squarely inside its own 50 to 60 day target. The discounts still did not come back, because the low incentive number is the goal rather than a symptom of shortage.   Plan your purchase around that reality instead of waiting for it to change. Follow our ongoing GM News coverage for pricing and incentive changes as the next-generation trucks land.

      Winter Returned

      By Grumpy Bear · Posted

      Thought it was raining this morning when we woke. Nope. Dew point was over 80 F and humidity 98%. Zero visibility distance. Everything was 'sweating'. I've seen rain come out of clouds but never out of Pepper or the tree trunks.    Wicked storms just missed us sliding off to the east but by blocks. Heat index about 110 F with air temp in the 90's.    This is  our third wave this month of multiple days of this type of weather. And yet the grass is going dormant and the ground is cracking this side of the street and water up the the hood opposite. Just weird stuff going on.
