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.

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.

      Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.

      Towing In Loose Gravel

      The thinking is that starting out in a higher gear makes it easier to avoid applying excessive torque when pressing the gas pedal. In a modern 4wd truck with 4 low and a limited slip or locking rear end, I would use 4 low and try to crawl up the ramp. Sometimes if they are too slippery, you have to back up to let the boat have some bouyancy, and then accelerate briskly to get some momentum to help you pull the through the slippery parts.

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.

      Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.

      Multigate electrical problem

      By Another JR · Posted

      The recall is for exactly this issue - those drain holes combined with the limited environmental capability of the tailgate electronics card inside the tailgate were a problem. The “safety issue” was the potential for the tailgate to spontaneously open, but all kinds of tailgate misbehavior can occur from water contamination of that control card.    There is no real fix yet. The initial recall just disabled the tailgate. Later, when parts became available, they would replace bad parts with new parts of the same bad design. My dealer is going nuts because the few times I let them get their hands on my truck, my tailgate is off due to a slide-in camper installation. They really want to cut my tailgate wires, but I won’t give them the chance. I will let them get their dirty hands on it when a real fix (redesign) is available.  My tailgate, which works just fine with sealant plugging the drain holes, will remain safe in a dry storage crate until then.
