It seems to me that, untuned, the slight hp gain up top is offset by the loss of torque, result is standoff on the dragstrip for my A8 car. Yes a tune could help, but it must be pointed out that a tune on a completely stock engine also gains 8~12hp and instead of losing torque, it gains some. Yes E85 helps, but I think you need to evaluate what each piece of the puzzle is doing when deciding what was worth the $$$$ and what wasn't. My feeling is, E85=worth it, MSD=not worth it. My perspective is from someone who is not planning to build this car into a 416 stroker with ported heads, a healthy cam, long tube headers, etc.
