Remember that your boost controllers and map/maf sensors will all read differantly. eg
on a profec B II i tend to find that 13.5 psi is 14.7 psi in reality.
I have done the maths for Gmogles run and the dyno is reading as close as you will get.
You cant compare 2 dynos on 2 differant days. There are too many factors that will come into play. ie temp corrections, altitude, temp, air pressure, rolling resistance, outside diameter of the tyres on and on and on

Dyno banter about May 13th @ APT
when people show me a dyno print out the first thing i do is pull out the calculator just in case the b.s flag is being waved.
