So... on a 5.3 crew cab 4x4... what sort of top end numbers are you seeing / anticipating after the delete? I know that the 4x4 police tahoes are limited to 121, and the 2WD versions with the lowered suspension profile are up to 139. The main difference is the tires are rated for the speeds. I am guessing that there are some other upgrades that they do not put in the highlights section like a better balanced drive shaft. I'm just happy that my truck will outrun something that is limited to 98, and even most Fords are limited around 100. I use my truck as a Security Patrol vehicle, and as a body guard transport, so short bursts of 121 are certainly appealing.
Mine will do the same thing if I jump in it and start it up, dump it in reverse and start backing out of the garage or out of a parking space quickly. I am pretty high speed, so ain't nobody got time for waiting for the camera computer to boot up.
I already looked into this, the answer is no, they just use their 0w-20 that is dexos1 spec.
It has nearly 100k on it with zero issues... whereas my Sierra is knocking on the big 5,000 and has yet to prove itself that it won’t blow an oil line as has been mentioned in this thread. That is why I think that...
You can click on the correct one for your truck (in my case at the far bottom right)... but having watched all of the videos, I believe that the unit that they will send are all exactly the same for each model.
https://boostautoparts.com/products/6hi There is a video on the product page. Do exactly what it says, exactly where is says to do it. The only tip that I can give you is that the horn relay (at least on mine) is also a brown wire with a white stripe, so make sure that you get the correct location, not only the correct wire color.
Boost Auto Module arrived and installed. Works exactly as advertised in a 2019 Sierra 1500. Wires are exactly the same color and place as the install video instructs, zero changes, zero problems. It even works with a Speed Turtle 3.0 Flash Module in case anyone looks at this later.
Wait... there are no bottom bolts on the grille on the 19 Sierra? No lower tabs that have to be released first? You don't have no remove that whole front trim piece that goes under the grille, headlights and over by the wheels? I am pulling mine on Saturday to install siren speakers and lights in front of the vents.
Oh... duh. I see that now. ETA: I called, they have not even looked at the 2019s yet. I checked the Body Builder manual, and the wire colors are the same for the two light control wires, and the positions in the wire harness are the same. I guess that I will be a beta tester for them and go ahead and order one. We shall see. Ordered. Should be here Monday.
It is out for the 19s... same as the previous version, as is it is nothing more than a jumper with a diode. They make a note that some models will have a different wire color, but that the position is what is most important. I also see the need for lots of light way out there, but also up close in the corners. Driving around the ranch at night with the truck pitching and bucking on the rough roads, I need a bunch of light everywhere that I can get it, and the dang grille shutters are preventing me from having a very clean install on any sort of covert grille mounted off road light... grr!
This is CRAP!!! We are driving to the Grand Canyon and Zion NP this summer, and I have been kinda fighting with the wife to take my new truck instead of her Highlander... Can you imagine being out in the 115* heat dead on the side of the road in the middle of nowhere Arizona with 3 kids age 7 and under because Pedro can't crimp a hose worth a damn? Not a safety issue? They can go straight to hell with that BS. Guess I will go start putting new belts and hoses on the Highlander... it will have close to 100K on it by July. Dammit!
I am glad that mine are power folding... they are at least 2" wider than my old 2008 Sierra, and I was nicking the 2008 about 2-3 times per year...
