I have a 2017 sbdc 4x4 Sierra with the 4.3l v6. I've leveled it with a rough country kit.  But as of right now, running stock size tires but will be going to a 33-34" tire. It has 3.42 gears and isnt and probably wont be underpowered. I plan to recalibrate the speedometer but in doing so, figuring it's just as well to tune the ECM/TCM. So anyone with the v6 running a trifecta, Vermont, black bear, diablo tune on your trucks. And have any input? Was it noticeable, do you run premium or see gains on regular? Good or bad for fuel mileage? My truck is a daily driver but does see some off road and work.

I have tried the Hypertech and Superchips on my 4.3 v6

 

Running premium fuel you will only get 8-10 horse and 10-14 ft torque. Regular fuel only 5 horse 7 ft torque.

 

If you want more power and can get e85 the factory rates e85 at 12 horse and 25 ft torque over regular fuel. Running e85 makes a noticeable difference.

 

With the superchips it does feel like it has more power down low. I don't like the Superchips 2-3 gear shift. To hard in my opinion.

 

I didn't notice much difference in fuel mileage.

 

Diablo, Edge and Superchips are owned by Powertech. Assuming their tunes are all the same as they rate the power levels the same.

E85 isnt an option in my area. So it's straight gas for me. I'm wary of the superchip... if it's just the one you plug into the obd2 port and leave it. But good to know that the difference was noticeable.

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      That is the funnel kit I bought and for being here in Canada I did get a better deal than what other sources were charging through a certain supplier in town that sources more directly and they ordered it for me. There are other items now on the market which would be perfect as well but this has worked well which was the hope when I bought it. I mentioned the Amsoil quart bottles as they have that squarish shape up top and it props nicely on the rim of the opening without falling into the funnel so I can leave them sit and drip a bit. You may have already figured out that to get the cap off the valve cover unless one is 7 + feet tall its not going to be reached without standing on a step of some sort and so when I do that I put the right adapter in and just leave the elbow on the funnel all the time anyway and open the lid and then if using quart containers for sure I can stand beside the truck and leisurely add the oil, and I can leave that funnel on when starting the engine to let it idle to fill the filter and then add the rest of the oil to top it up before removing the funnel and putting the factory cap back on. I put the cap back on the top and slide the bottom cap on as it fits onto the elbow adapter also and then store the funnel in a clean household plastic garbage bag along with the adapter so I have no reason to be washing out the inside of the funnel as I keep it completely clean between uses.    Draining the oil as per the under the truck portion, yes indeed that is slick as someone was thinking on GM's part there and admittedly I don't drop the oil screaming hot in this truck due to the exhaust being there and makes it safer as far as the oil temp if its just warmed up some instead as I don't have the truck on any ramps etc as I do it as the tires sit on the garage floor. The filter is not boiling hot then either and can drop it off into another pail after pulling the drain plug and just leave it drip out. Go back under a few hours later with new filter in hand and clean off the filter base and put the new filter on and install the drain plug. The filter is a little cramped in there as per wrapping ones hand around the filter and I am so used to using the band style filter removal tool that its no big deal and same for snugging it up. My filter wrench is many years old now but I think this is the current version and sounds like the right size, just in case my explanation was not great ( those nylon strap wrenches that one tool fits all filters are not my favorite tool to use, I much prefer this style personally )     57020 Swivel Gripper - No Slip Filter Wrench - Small | Lisle Corporation   And again about the oil draining and filter setup under these GM trucks, I've watched Ford videos of them struggling with oil flying sideways out of the oil pan on the gas 7.3 due to the sideways drain plug onto other components or cross members and guys trying to make shields out of carboard etc and other Ford pickups that Ford insisted they have sideways drain plugs. One win for GM there anyway with this engine.

      Kind of off topic, wife drives a 2023 Yukon Denali with the 3.0, been a great rig so far, incredible fuel economy for a truck that big and heavy. Coming up on 50000 trouble free miles.

      Valvoline R&P Fuel System Cleaner

      By PunchT37 · Posted

      I`m gonna try some of this in my 2000 LM7 that has had the famous piston slap since 17,000 miles or so. I have used Mopar combustion chamber cleaner down the spark plug holes a few times in the past. Corrects the problem for a few months or so. Then returns. GM top engine cleaner has been used also. No good results from this.   This LM7 never used oil. Even running the piss out of it.   Course, I`m gonna use this in my 2025 L84 while it`s still clean. It`s got 13,000 miles. Used Chevron fuel system cleaner [2 bottles in tank] a tank or 2 ago.
