As for Laguna Seca, remember, different events have different sound limits. The 92dB days are pretty much stock exhaust only.

Yea 20" away from the exhaust at some 45 degree angle. The standard suggest somethign like 50-75% RPM of max red line but a lot of new cars don't let you do that when stationary anymore. I can't find any proper information on these that do not require buying the standard J1169 from SAE.org.
(Typo with 68 in my early post).
Yea, its really sad for Laguna, since T5 is uphill and chances are the car is full throttle high RPM at that point where the sound booth takes it reading. There is a reason these exist:
