Has anyone tied this to the hmi module at all? Mine died in my 2014 and I went with one of those companies that sell the newer ones programmed for your truck so I could add android auto and apple car play. I have all of these symptoms now, except for the wheel jerking (never had any before the replacement hmi). I did the ground modification, removed my amp/sub and removed my brake controller so there are no more 3rd party accessories any longer.

I don't think Black Bear has made any claim to getting around detection. So far to my knowledge only Diablo has.

I got basically the same response back from Lew also, saying it's because they have a GM Programming Engineer on their staff... It's got me leaning more towards that way, just wish we had a way to confirm that.

I sent an email to Diablo asking about how they claim to not void the warranty and got a very short answer back.. Anyone have anything more on this since everything I've been reading in this thread and others seem to indicate otherwise...

I got a deal on my 5.3 14 Silverado but it had the 3.08 in it. I will need to tow possibly up to 7000-7500lbs sometimes so I've been trying to decide on swapping to 3.42's but the tune has been something I've been worried about after doing that. Reading this thread had made me really want to tune it and since I'm in NC PCM of NC looks like a great idea. Curious though, do you think I could get away without changing the gear's with a tune since that would adjust the transmission pressure/shift points? Or would that not really impact the towing capacity? Thanks, JB
