Default dyno results (kinda) and dyno question

first the question: does the 2004 m3 need the gt1 unit to do the dyno properly? i tried doing the DSC trick, unplugging fuses but nothing worked. it cut out at 6250rpm.

my results: at 6250rpm i was doing 253whp (which i thought was good for 270whp if gone all the way). torque peaked at 230 (don't have the dyno sheet on me.)

does it sound good for completely stock?
it was done on a dynojet, it was around 23c and i'll post the chart later this afternoon.

I am pretty sure that a GT-1 or similar device is required to accurately dyno the E46 M3.

Using some simple math (ratios) based on the numbers you have provided an assuming a 20% drive train loss, at 253 RWHP you're looking at 316 @ crank. So I would say considering the RPM that you're right on par with what is expected or even a little higher than others.

tag racecraft in oakville.
price was $50 for 3 runs. but that was an organized dyno day through maxbimmer.
i think if you have some sort of software done you might be fine. but the looks of it i think you need the gt1 unit to bypass it....or something like that. still trying to find out.

here's my graph.
