I recently got a tune done via Hemi Fever through my diablo i3 (2009 charger R/T). The tune works PERFECTLY when put on. But then once I shut my car off, it stops doing the burble from there forward, but seemingly stays on the tune. He's sent me two different versions and cant seem to fix my issue because he's never happened before. The thing that seems to be the issue to me is that when i shut the car off, something reverts back to "normal" and therefore stops the burble part. Any one have any advice or possible fixes?
