These are things as I understand them. I didn’t wanna get in the weeds. And I am not a tuner but I’ve dabbled a bit. You’re always going to see a little KR from time to time, even on 93. The ECM wants a certain number of degrees advance. But load, humidity, ambient temp, fuel quality will all vary, and sometimes it needs to pull back from it’s target. This happens well before any audible pinging or damage can occur. And there is a decay algorithm programmed in that will reattempt to hit the maximum timing after a short period of time. Basically it’ll continue to test the limit. So with that in mind, if you AREN’T running into KR once in awhile, you’re probably leaving power on the table. On the flip side, if you are driving around with 8 degrees of timing pulled all day because you saved 20 cents a gallon on 87, you are also leaving a lot of power on the table. Is that alone going to kill it? No. The ECM is only going to pull so much timing and not enough to harm it. But I think the reference about audible pinging in the owners manual implies that there are possible situations where the ECM cannot compensate for your pennywise fuel choice. Hot day, pulling a trailer, bad gas, any number of things. And then you might be risking screwing something up. But my main argument is not that you might blow it up, it’s that you should get the power you paid for.

Maybe next week someone will spend $3000 extra on a Trail Boss and then ask about lowering it 2” to increase MPG.

Have trouble seeing the sensibility in saving $5 a tank after spending 60 grand on a truck with the largest engine option that you use to get groceries. Talk about closing the barn door after the cows got out. The big money is already spent, so enjoy it and get what you paid extra for.

Yeah, they expanded 10 speed availability, but not until 2020. Chevy gets it in the 5.3 LT TB and 5.3 HC. GMC you can get the 5.3 10 speed in all but the poverty trim. But things have been a little sketchy with all the supplier issues. A lot of the 5.3 trucks that were supposed to 10 speed got stuck with the 8 and a $200 credit. What a deal.

I didn’t say running 87 would damage it, I said it didn’t make sense. People don’t bat an eye at spending 50k+ on a truck, $2500 on the engine alone. But when they get to the gas pump, all of the sudden that 20 cents extra is financial suicide? Sounds pretty goofy, no?

He has a Whipple so he definitely needs 4WD. But even without the blower I think it’s pretty much required for the best launch. These trucks come out of the factory on tires that are hard as a rock for fuel economy. Couple that with no weight in the bed, especially if you drop the spare out. General consensus is it’s best to launch from 4H and then shift to 2WD once you get off the line. 4 auto allows a slight amount of wheel spin at first. Plus since the front axle is always engaged, you don’t reduce any drag using auto instead of 4 high. On the street, I always use auto for launches, but you kinda gotta turn sometimes.

Arguing just to argue at this point. Good grief. Performance is performance. Whether it’s so you can accelerate faster with a trailer or accelerate faster without a trailer. Makes no difference, I left it a broad term. Besides, I don’t think their engineering department specifies how you need to use the power. Their engineering department does specify a fuel type though.

I know you think it’s silly to have a fast truck. That’s fine. But the purpose of the 6.2 option is performance. The only reason it exists. So if someone buys it, they should want everything they can get out of their added investment. Put it different way while beating this dead horse…If you’re that concerned about saving a few bucks per fill up by running the wrong gas in your 6.2, wouldn’t it be smarter to save $2500 and get the 5.3 instead? It not only uses 87, but it uses a lot less of it too!

My experience too.

So will you be putting 87 in the Vette, or will you want the power you paid for by using GM's recommended fuel? For me, it makes sense to get my kicks from a truck that I can drive anywhere, any day. My TRX should be built by the end of the month so I can take that even further. All while everyone's Corvettes are sitting in their garages because the car has zero practicality and they treat it like a museum piece. Take one person at a time for a ride, but only in the summer and on a sunny day. Sounds like a riot.

Do what he did. Best time I’ve seen from these trucks. On the street, 4 auto and just mashing the gas has given me my best 0-60 times (measured with Dragy). Personally haven’t had much luck with brake torquing. This truck just kinda falls on it’s face when I do it. My 2016 did the same thing.

Performance is the only reason people buy the 6.2. Whether it be for towing, or for stoplight acceleration, the engine exists solely because it makes more power. Sure, “fast” is a relative term, but 0-60 in 5.4s is much quicker than most vehicles you’ll encounter on the road, including an Accord. I certainly have fun with my truck and want every ounce I can squeeze from it. If you spend $2500 extra on an engine option in a $60,000 truck, but then worry about 20 cents a gallon, your priorities are a little screwy anyway. Like the people who eat a triple Baconator for lunch but feel good for getting a Diet Coke with it.

Mine has done the same since day one.

I don’t run hard or tow in the winter and have a lot of idle time, so I usually use 88 E15 to putt around and it’s just fine. BUT I do not cheap out with fuel in the other 3 seasons because I paid for the 6.2 performance and want to use it. These engines pull timing like crazy on regular. Even the 5.3 does.

All 7” displays are IOR. IOR is the only available infotainment in Custom.

I’ve tried very hard and I cannot get 5 MPG no matter what. Lifetime is around 13.

Yeah but now there’s ANOTHER blank switch where the disable button used to be.

I’ve been enjoying the past few months of having been proven right on everything from the start. And now covid is as over as it can be. A few are still clinging to it, but it’s over. My observation is that people are just done. The vaccine has done amazing things, but so has the truth as it trickles out over time. Everyone can see how much they’ve been taken for a ride by media and politically tainted health “experts”. Even up here. And even if they don’t wanna admit it. Real science and the truth wins in the end. I guess that’s pretty much all I have to say on the topic. Just to wrap up my opinion on it forever. Spare time was never easy for me to come by mainly because I don’t seek it out. Running my business 7 days a week. New truck should be landing sometime in July and we’re hitting the road on a short vacation right away when it does. Guess they are just flat sold out of premium in SoCal right now. Hope it stays in supply around here. And also below 5 bucks would be great. Everyone here, have a good summer and make up for lost time if you can.

Still just a $300 difference on the Chevy side.

If you have a sliding rear window, keep an eye on it because a leak might be expected at some point. But beyond that, the issues you’ve had don’t really mean you have a piece of junk that’s gonna break down constantly. Stuff happens. Vehicles are more complex than ever. I’m on a lot of groups and the same thing happens to all makes and models.

High Country, or better, Sierra Denali, would be the closest to the Limited. Obviously still not as nicely finished inside, IMO. Once you get up to either of those trims there are not a ton of option packages to be added. High Country has the Deluxe and Technology packages, and the Denali has the Ultimate package. Might as well go all the way. 10 speed would be standard on either gas or diesel engine in those trims.

Pretty much hard to find anything anywhere at this point.

Depends. The base level 8” display is the same as the 7” as far as features. But there is also a midlevel version of the 8” standard on LTZ, and available as an option on LT, RST, and LT TB. It is known as the “plus”. The ”plus” 8” is considerably different. It has a higher resolution screen and backup camera, HD radio, XM360L, and wireless CarPlay / AA. Lastly, there is a top end version of this “plus” system with embedded nav, optional LTZ and standard on HC.

If it’s a rental, no repair is crucial.

How I look it at…if something breaks, fix it. You can make anything last 20 years, or even forever, as long as you’re willing to fund maintenance and repairs as you see fit. That is, unless you live in the rust belt. Then you might not have a frame left to bolt new parts onto at some point.
