Does anyone else's exhaust make a burp or popping sound at idle? Ever since I installed the 2018 GT manifold (IMRC's locked) and uploaded the FF tune, I've gotten these exhaust burps. So far, I've only run 93 octane, so I can't vouch for E85.
I have a friend who told me the exhaust burping is normal with the FF tune, but I wanted to check with you all.
If nobody knows what I'm talking about, I'll try and grab a video later tonight.
