I've been running one on my challenger with a procharged/fuel injected 340 and a Tremec TKO for at least 7 years and over 50k miles now. It takes some getting used to but is pretty sweet. It revs like a sport bike and has amazing throttle response. You do have to pay more attention to clutch engagement but I kinda like that aspect of it. The only issue I have had is that sometimes when rolling slowing to a stop when I put in the clutch the engine will die before the efi can cacth the drop and return to idle (dfi gen 7)
