Hey guys. I have a 2015 GT PP and I recently did a ported 18 manifold with imrc lockedout, an 18 pmas, and lund tune. Car pulls strong, but at idle it has a very obvious stutter in the exhaust and there’s a loud random “pop” coming from the intake tube. The car has 45k miles and I swapped to a throttle body from a 16k mile 2016, and it didn’t change anything. I deleted the evap entirely and datalogged with lund, they sent me a revision and said everything looks great but nothing changed. I checked all my vacuum lines and can’t find any leaks. Anyone else had this issue? Any suggestions? Thank you
