I am not going to stoop down to how many varied tuner's SC applications have failed ..the point of the post expressed by VVG is vaild on its face either you accept it or you dont and if you dont then feel free to express how any of his points
dont have a basis in fact.

2. Your margin for error while driving becomes much less. While a mis-shift, an over rev, etc, etc, may be tolerated by a stock motor, it may not be by the boosted motor.
3. Over the years I have seen blown motor after blown motor on all sorts of cars with all sorts of kits. Sure it can happen on a stock motor too, but the risk is just that much higher when boost is applied to a previously NA stock street motor.
4. If you want to go forced induction, buy a forced induction car from the factory. I guarantee you that the tolerances for the internals are such to allow a huge increase in tuned power without much worry. A stock B5 Audi S4 which came from the factory with a 250hp twin turbo V6 could be easily tuned for over 450hp and almost 500lb-ft of torque on the stock block with bullet proof reliability.
5. If you want to put FI onto a NA street car, you need to build the motor...crank, pistons, rods, rings, and run a CR of certainly less than 10.5.
Do it right or don't do it at all. While I feel for the OP, let's be real. Is anyone really surprised that this happened? I hope not.
