Dude, i wouldn't run less than 91 octane with the premium tune. One hard day of driving and your engine will hate you forever.

I run afe cold air intake with throttle body spacer. On the tune I run 75% firm, 100 over stock on Rev limiter and 100 over stock shift points 1-2, 2-3 and 3-4. Above fourth is stock shift points. Premium tune with 91 octane. Seems to run great. Oh and with no top speed limit it's nothing to hit 200 km/h pulling out to pass. The tune really helps out at the 3500 rpm range pulling a hill or passing, it eliminated most of the lag. The throttle response is crisp but the intake and spacer are to thank for that. I recommend hypertech if your looking for a smoother responding machine with a bit more pull than you had leaving the dealership but is definitely not going to make you dragster. I also found of you drive sensible on the highway it improved my gas milage. With 33 inch mudders I can average around 22-25 mpg which in M.O. isn't terrible for a full size pickup. The dealership claims I should get 30 mpg but when has any dealer told you the truth...

If your talking about E85 that's above 93, you run that its good for 25HP on a stock 5.3. If you read your hypertech instructions its in there.

Oh i thought you meant you run 85 octane with the premium tune. My mistake. I've heard horror stories of guys only running 83 or 85 octane on the premium tune which destroyed their engine after a night of heavy driving. 91 octane fuel is most common at the pumps were i live, from what i was told anything below this grade will not be compatible with the hypertech premium tune. I've ran 94 and didn't notice much difference in m.o.

if i were you id pull that throttle body spacer. worthless.

How so? Increased throttle response and better fuel milage after install. Worth the $150 pocket change to me.

150 for tb spacer? you do realize these trucks have direct injection right? that means there is no air/fuel mixture that a tb spacer creates more time for combination. all you're doing is giving air an extra inch before it goes into the cylinder. direct injection means the fuel is input at the cylinder not at the throttle body. your spacer does absolutely nothing. actually 100% of nothing. i'm not being rude, just factual.

Your facts seem right but I don't think it's about the timing for the air to mix, its the motion the spacer creates to help with turbulence as the air and fuel mix. They claim it helps to achieve more "complete" combustion as the air leaves the throttle body and mixes with the fuel at the cylinder, nothing to do with timing. The combustion reaction is achieved with more efficiency when there is a demand for fuel and air when the operator steps on the pedal which gives the machine a quicker response. The time it takes for the reaction to take place is improved from the spacer install; but like you are trying say, the time the fuel and air have to mix together does not change. It's the "motion" of the air as it mixes at the cylinder that improved my throttle response which takes no facts to prove because I drive my truck everyday which is reality, not fact.

Here's the "facts" on how this spacer will work for the ecotech engine, or any fuel injected engine for that matter. Nothing about timing.

No facts, just a product page from a company trying to sell you their product.

Well for those who don't believe all i can say is throw one in and light em up. I break traction far more than ever before I installed it. Don't see any facts saying it doesn't work either...

Do you not understand what direct injection is??? You make no sense, we all buy stupid stuff sometimes but seriously dude you are doing nothing here...

keep it if you like it. it doesn't affect direct injection i dont care what they say.

 

if i were you i'd just port my intake, thats probably more bang for your buck. although it hardly makes any difference. if i were you i'd spend every penny on a custom tune.

    • The “engine hours” display is there because the truck detects the key presence as you were thinking.   My first step would be to call a dealer service person and ask if this a known issue and how they deal with it. If you don’t get meaningful advice there, i would try a couple of DIY things before bringing it in for troubleshooting/repair.   It sounds like a mechanical key detection switch is stuck, but I have not actually seen what the internals look like. Maybe spray some Caig Deoxit (electrical contact cleaner) in the key hole and work the key in and out in case it’s an electrical contact cleanliness issue.  If that doesn’t work, next apply whatever lubricant GM recommends and work the key in and out a few times.    Good luck with it. 
    • Carbon on valves would be the least of my worries on a light duty, 1500-series pickup with 357k provided the engine still ran halfway decently. Everything else is likely toast, on its way out, or has already been mauled to death by cheap mechanics and backyard fixes. Those kinds of trucks nickel and dime a guy to death.   I wouldn't think having the top end cleaned once or twice would be a big deal on a 5.3 but maybe it is?
    • I wonder how much carbon is on all those high mileage valves?
    • When I had a Bumper subscription for a few days when I needed to run title histories on cars I was looking at, I decided to look up a few of my old/past vehicles.   My 2015 Silverado was still actively registered and it last sold in 2024 with 160k on the clock. No idea if that's on the original engine but someone's keeping it on the road or the original AFM stuff is still going.   It used 0w20. I remember feeding it Mobil 0w20 AFE for the first 30k of its life on <5k OCI's.     Edit: Just did a nationwide search on Autotrader for 2015-2025 Silverados with 5.3's and sorted by highest mileage first.   357k 352k 292k 291k 290k 277k 271k 268k 266k 259k 256k   High mileage on a modern 5.3 doesn't seem all that uncommon, but that's just searching mostly dealer ads on Autotrader. FB Marketplace has all kinds of high mileage 5.3's going back to 2007    
    • I can't say I have ever heard of someone getting that type of mileage out of a set of tires even though they rotated on a regular basis but without a doubt if the front end gets wear and those tires are no longer able to track straight it scrubs them off, and driving style and road surface make a huge difference as well.    However that is not what prompted me to comment as it was the new tire theme of sitting in storage waiting to be used scenario. I am sure some tires can last for quite a while in storage if its not too warm and out of the sunlight but unfortunately some tires the way they their rubber compound is formulated they can age and dry out even in a reasonably decent storage location. My brother ran into this maybe three years ago when he was looking at the tires that were on his dually truck and a combination of wear on the rear ones and noticing that the front tires had some cracks around the sidewall of the tire not far from the bead but he had replaced only the front ones not long ago with 2 of the remaining 6 he had left from the initial two sets of takeoffs he had all bought at the same time .... 10 years ago ! ( the years fly by, a truck that only gets used a bit to haul a camper during the summer and sits in a shed for a large part of the year ). That second set of 6 tires, two he had put on the front prior like I said and they had very little wear but those cracks were now present. So we go into the shed where the other 4 tires had been stored all this time and every one of them had the same cracks in the sidewalls and so in the end it amounted to throwing away 6 brand new but 10 year old takeoff tires into the dump that he got a deal on at a tire shop because they aged out. They were a Ford factory equipment BFG tire and those tires did not age well compared to some tires I've seen far older then that and did not show that type of aging. True, they always say up here anyway that 7 years is sort of a limit for age by rights, we don't have the intense prolonged heat that many of you have down in the states that just cook tires and depends on where the vehicle sits when not in use. GB, another words maybe had you bought a set of tires to store it would have been fine as long as you used them up fast enough but there are no guarantees when it comes to rubber, tires or of that other type stored in some guys wallets 😆
