**Specialty Tunes: The P1 Tuners Ghost Cam tune and Pop Flame is a core set of tunes included in full package and multitine. We've invested a lot in perfecting each of them.  While we don't offer these as a novelty one and done tune with no revisions as we pride ourselves on the Ghost Cam and Pop Flame Tunes we offer and will revise them as needed, we can't guarantee chop sound, drivability, no stall, pops in neutral and or flames.  With this said, we think you'll enjoy these as a part of our full package and are ready to customize them to your vehicle!**
