  1. Ordered an ecm to send into HP to help reduce how long truck will be down. Still havent ordered the supercharger yet. Im thinking Whipple, although the easier install of the procharger is nice. Anyone install the Whipple themselves? Just wondering of any pointers beforehand. Any tunes out there better than the Whipple tune? What other mods/upgrades has anyone really liked? I've always built lifted trucks, wheels/tires, etc. I'm going for a bulletproof high power build on this one.
  2. One other thought ive been debating on... should i put on some headers while im at it? Ive got the gm performance cat back, but id headers and better flow will help power and keep temps low, plus add some throat to the exhaust sound. They can also be a pain to install. And after i broke off a rear passenger side bolt and fought exhaust leaks when i put shorties on an old 350 K series, i swore id never mess with headers on a daily driver again.
  3. I started out initially leaning ProCharger. Did some thinking and decided on Whipple. After more thought, i remain undecided. I know overall, whipple delivers consistent power increase. You'll get the boost even at low RPMs. I was then thinking i wont be pulling or hauling too often, and running lower boost at lower rpms might actually be more ideal (less engine wear, tire wear, drivetrain, etc). Some other differences.. ProChargers tune is easier to install, they have an arrangement setup with HP already to streamline the process. Procharger install is less invasive overall as well. With Whipple, you have to go through HP Tuners and get ecm unlocked, and then upload the Whipple yourself. Part of that process is more involved. Security/immobility relearn requiring a gm dealer (mdi2) tool. All that being said, since both are good options, I'm stuck at a crossroads... pondering...
  4. Did you buy an extra ECM to prevent the truck from being down too long? Just wondering where to buy from. Also, do you know if you had the TCM (transmission) tuned at all? Thanks
  5. IMO, it is as simple as bolting it up and uploading a tune. It didnt use to be that simple. Tuning is exponentially more than it once was. Torque management can protect drivetrain, shafts; etc. Obviously upgrading the bottom end may be a good idea, but i dont think its needed. I also came here for ideas though.
  6. I've been watching the developments on superchargers and tuning since i have first driven my 2019 6.2. Not because it needs more, but because i want more. Either Whipple or ProCharger. I know there are pros and cons. What i havent decided is what other upgrades are needed. I like to make things as bulletproof as possible. What engine upgrades, driveline, etc are suggested? Please be as specific as possible. Id like to avoid pulling the motor, but everything else is fair game.
  7. Any updates from anyone? It sounds like my "squeak" is getting louder. Currently around 2600 miles. I did have a CAT back from GM installed to try and drown out the annoying squeak, but it didn't help. At least the good news is, the exhaust itself sounds awesome.
  8. GM sells a wireless keypad to lock and unlock the truck. Its 125 bucks and has 2 way tape on the back. Mount it inside the fuel door- too bulky to stick on a door. Lock truck with fab inside.. use keypad to unlock when coming back. Outside of 3rd party work arounds, that would be the cleanest fix i can think of. https://www.shopchevyparts.com/electronics/2019-silverado-1500-remote-keyless-entry-system-keypad-433-mhz/23473341-p-92300642.html
  9. Any updates? I’ve been waiting to return to service hoping there would be a solution.
  10. It will be interesting to see what the solution is. Not the end of the world, but irritating on an otherwise perfect truck. I did use the squeak as an excuse to put on a cat back. Still hear the squeak, but now there is a good throaty exhaust behind it.
  11. Hoping a solution is found... the 6.2 qand 10 speed is an awesome combo. The squeak is mild, but not the typical type of noise id say is acceptable. Im having a cat back installed next week, ill see if the dealer can take a second look. From what i could tell, it was exclusive to the passenger side, and seemed to be coming from either the exhaust manifold or potentially the o2 sensor just down from it. Could even be a heat shield thats rubbing when the engine is at the right rpm range causing a vibration. Troubleshooting shouldnt be too hard, but i was by myself. Need to jump the rpms to the 1200 range once warmed up.
  12. I’ve got a 6.2 hc with same issue on startup and cruising at same rpm range. Dealer said they didn’t hear or couldn’t replicate sound. Let us know if anyone finds a solution. Sounds like a pulley or even a small exhaust leak on passenger side of engine
