Another point of view (from a simpleton):
Something went wrong with an expensive engine, ie, big money has been spent on it.
I myself, would never spend such an amount on a car and thus, the problems associated with in-depth tuning and the like wouldn't apply to myself and most of the people here.
Most of us want new exhausts, cams, AFC's, dyno runs and the like. Simple stuff so to speak. Therefore most of the slandering that goes on I take no notice of.
Don't know if I'm making much sense but that's how I see it.
