Get an un-altered one, tie it down on a chassis dyno. Average drivetrain loss for a stick car is 15%. 20% for an automatic car. If it makes more than the claimed rating at the tires, start with that. It would still be a little soft but guys couldn't cry about the drivetrain loss factor being wrong for a particular vehicle.

I don't agree with the pump gas deal at all.
