Deff possible that Mazda underrated the car. At this point, we have a wide enough test base to accept these numbers as what it should be producing I think. I have also dyno'd a Speed6 and another Speed3 with similar results. Those cars were also mostly stock.
On the EVO 8 and 9 end of the spectrum, our cars seem to read lower than most other peoples. A stock EVO will make about 275ish on our dyno and with some tuning, the car should make around the 300wtq and 300whp area for a simple compairison.
At the end of the day you must remember that the dyno is a tuning tool first and a benchmark tool a distant second. There are various ways to calibrate various dynos, and few of them will spit out the exact same number.

I thought I had read that too somewhere. I thought I was just having a 'brunette moment', maybe not.vindication said:

But don't dealers see when the ECU was reflashed on an OBD scan?Chris@AMS said:
But the boost cut can be eliminated. These engines tune off of MAF and MAP sensors.

did a quick search.....http://www.automobilemag.com/features/0610_gti_civic_mazdaspeed3_dyno/mazdaspeed_3.html
edit: also, Xede cant be that bad if begi managed 57whp and 70 ft/lbs of torque with just the unit....either that or mazdas down tuning on the cars ceases to amaze me.

Regular OBD scanners can't see a reflash.
Correct, the motor does run off the maf sensor, and according to another memeber this is the sensor it uses to enable boost cut. If this is true, boost, or even flow from a larger turbo will enable the boost cut and make it very hard to tune with a piggyback.

I dont know if it is or isn't but bell engineering is well known and respected and Mr. Corky Bell wouldn't fudge info I dont think
I think it is clear to say ECU Flashes/Piggybacks opinions are like as*holes. Everyones got one. I dont know I am completely torn in two as to which one I will go with. Am I the only one thinking this? I did talk to Cobb today and they said they really dont have any info on the Flash, they are expecting to see the unit out by spring. We will see about that!!!
