    What did you do to your 2015-2020 K2XX Tahoe/Yukon Today?

    Got about 150 miles in on my BB tune and it’s a sleeper. Throttle response on highways or accelerating is very noticeable. In my city driving I’ve noticed that the transmission is less jumpy. I also have a 92oct tune I’m gonna give a try but have no idea what it’s for lol. I don’t tow or race...

    issues with e85 ?

    I’ll let you know what BB tells me when they respond. I use E85 every so often for the cleaning benefits as it’s about the same cost as 87 but burns up faster. I’ve never ran super unleaded in mine.

    Which engine do you have? Do you normally use 92 oct.

    issues with e85 ?

    I think it depends on the tune. Recently did my tune and I have an 87/89 tune and a 92 high octane tune, which I assume is for running E85, since I have the 5.3 flex fuel. I did send BB a message asking for clarification.

    Last night I found my BB tune files hanging out in my spam folder :mad: . They were in there a few days so I hope they didn’t get influenced by bad actors. Got them loaded and took a quick test drive. It’s about time. If anybody needs a gently 10k used Range device let me know.

    What did you do to your OBS GMT400 Tahoe/Yukon Today?

    It’s never left me stranded or overheated but they’ve all started leaking at the plastic sides. Maybe I’m just unlucky lol usually about 24 months in I have to start adding at the reservoir to keep it filled. Once I’m filling it back up each tankful I start planning on putting in a new one.

    Changing the radiator for probably the 5th or 6th time since 05. Radiator is definitely a weak point. Went with a local radiator store that has a lifetime guarantee. Was going to go with one from them about 10 years ago and here we are now :mad:

    Brand New Yukon - Warning light driving home from dealership

    I’m rarely in my car without my phone, why not just use your phone maps? I bought a pre-owned and I have a detailed travel history of the previous owner.

    What did you do to your 2015-2020 K2XX Tahoe/Yukon Today?

    Got the data log done and sent all the files to BB without bricking the truck so far lol. It’s been more intimidating reading the instructions that actually doing it. YT is great because I’m kind of a visual learner. Once I see you do something Im usually more able to follow you than if you just...

    Valvoline Restore & Protect experiment

    I don’t use it much during the colder months but May to September I try to run 2 or 3 tankfuls. Some say it might be more beneficial to run them back to back so I may give 2 a try and see.

    Need vehicle opinion other than my wifes

    The difference between my Yukons lengths are almost a foot so I’m surprised the burbs didn’t grow as much as well. That’s good to know

    The newer ones are probably more than foot longer than the older ones.

    Valvoline Restore & Protect experiment

    I have a flex fuel vehicle and kind of agree with him, wouldn’t call it a scam tho. I have the 5.3 and I run a couple of tanks per year during road trips for the benefits to the engine. E85 costs about the same as 87 near me. I also don’t drive it daily and I hear E85 is not good for garaged...

    I tried to data log for my BB tune today and my autocal won’t data log for some reason. I messaged BB so it will be a day or so before I get a SZ response. Definitely miss the old in person tunes. Would have been had this done if that was the case. I imagine due to the errors and only being able...

    Is the release pull still in tact? Mine broke years ago so I black the locking mechanism when it’s in the seat position.

    I hit mine with a heat gun last cleaning and it worked for a while. Gonna try a couple Velcro strips on the problem area next time I clean them and get a chance to shape again.
