HDDP I think you misunderstood my question. I want to know that from your experience do pulleys do anything at all? Because there is a set available from Kleeman that goes with this ECU upgrade but I don't think they have dyno sheet for it. Together that would be nice.

And how is a crossfire putting down 160 hp at the wheels, that is just insane. There have been Porsche 944S2 dynoed and have put down 180 to 185 at the wheels and those cars have 208 hp stock. There can't be that much driveline loss in the Xfire can there?

HDDP check this out, this comes from the Startech catalog. Is this HP numbers possible with these upgrades like they claim?
