Its very useful for comparing relative horsepower gains between various tunes.

And, to promote Bench Racing at its worst, here are some numbers:

Stock 14b, 13psi, 2.5" exhaust, hard UICP: 140.0hp @ 5109 rpm, 136.4 ft/lb @ 3514rpm

Evo III 16g, 18psi, 2G MAF, same other mods: 246.5hp @ 5275rpm, 225.8 ft/lb @ 3675rpm

My boost gauge only goes to 20psi

And my clutch slips over 20psi, so the readings wouldn't be accurate.
