  1. Resonators gone new mesh screens replace them

    My 19 HC also has resonators like this.
  2. 6.2L fuel

    E85 is not an approved fuel for the 6.2.
  3. Just noticed that every time I back into a steep driveway that requires the rear suspension to articulate to one side there is a pronounced suspension clunk and bushing noise. This is a pretty extreme articulation even for a driveway, but was curious if anyone else has a similar noise. Suspension is Z71 on 20inch tires. No noise if both tires hit curb at same time. Similar noise is produced when exiting and turning making each tire descend the curb individually. Thanks!
  4. My High Country has also done this on several occasions under different version of the software on the head unit and the iPhone. The only solution I have found is to turn off the truck and leave it for a few minutes and then restart it. It's a huge pain, but that is the only thing that has worked to correct it.
  5. 2019 5.3L ECM Tuning

    Perhaps we are getting closer to being able to tune the 6.2. Not sure about the 10 speed transmission though. http://hennesseyperformance.com/715-rwhp-2019-zr1-corvette-tuned-by-hennessey/ Mike
  6. Radio Proflie Deleting

    Happened to me two days ago. I signed back in and my profile download form the cloud. I did lose the Messenger App (never ever go it to work anyway), Weather Channel and Spotify. I had to re-download these two apps. The computer gremlins on these trucks is a nightmare. I have to wonder if our new trucks are the ginny pigs for the new systems in the C8 vettes that have been giving the engineers hell. I love my truck, but never know what message will pop up, what view from the camera will default or when my profile decides to delete itself.
  7. T1 Switched Power Source

    RAP only stays on until the driver door is opened.
  8. Power programmer

    Does anyone know how Hennessey is supercharging 2019 silverados without the ability to program the ECM and tranny?
  9. Ever since the last update, every time I get in my truck the DIC displays a waring that User 1 Profile is in use and requires that I dismiss the warning. Anyone else experiencing the same?
  10. Happened to me last night too. The Radio was playing in the background with any other source as well. I tried turning it off and back on and it didnt correct it. I let it sit for 30 minutes and it cleared itself. I love this truck, but the damn software bugs are driving me crazy.
  11. Serice Steering Column Lock

    Same thing happens top mine.
  12. GM Performance Exhaust is manufactured by Borla from what I have read.
  13. High Country LED Cluster Goes Blank

    I had the service bulletin performed. My truck required the cluster to be replaced and reprogrammed. I am happy to report all appears to work now without blanking out. Even the chevy bow tie graphic displayed on the DIC doesn't blink when I first enter the vehicle now. The fix works.
  14. T1 Switched Power Source

    No issues on my truck.
  15. Front and rear camera park assist

    On the camera app; bottom row of view selection on the far right is an arrow pointing to the right. Touch it. On page two there are two selections. One of them toggles between hitch guidance asssitance with a single line and the other is the box you are searching for.
