My thought was perhaps using a calibrated instake
restrictor and computing theoretical changes in
airflow with and without it, tuning with it on the
dyno to keep power down, and then using the math to
calculate theoretical values for the unrestricted car.
 While it will be far less than perfect, it most
likely would leave the car drivable enough to be able
to map out through drag runs, without having to waste
too much time fiddling to get "in the ballpark" at the
strip.  Dunno it if has a lot of merit, but it's a thought.
