  • I was just going to drill a hole on the gasket right by there, was there a reason you drilled through the fire wall instead?

      I couldn't get the grommet to come out and I didn't want to rip it. So I just drilled it and filled it with clear silicone.

          No, it will fight the JB4 on canbus and lead to issues.

                  • What type of run are you looking for if I wanted to send a log? Having similar issues with flutter in 3rd gear at high rpm's.

                        There is no popping. I’ve had the spark blowout as well but what I feel with this issue is more like it just stalls out at a certain rpm and quits pulling.

                          How do you have that running through your carplay?

                            I bought an android TV box from Amazon. Let's you download apps and use them on the carplay app.

                            • I know this is a Cadillac thread, but I can't find any info on my truck, so was hoping to get some help here since my truck has the same engine as some of the cars mentioned. My question is what software do I download to be able to tune my JB4 on my 2022 Chevrolet Silverado 2.7 Turbo? Are there any tutorials on how to tune it for this particular model?
