Didn't do a before run, the software was done the day before the run...
The only other dyno run was closer to the end of last year, the car made 173/175 on Sav's Speed's dyno, which I didn't think you can compare to the the dyno at KAR... i.e. teh conditions etc where different
Honestly...the figures are a "nice to see"... on the the road it's where I can really feel the difference...

Glad you happy bud.
Kabal, we didn't get a chance to dyno before, but the car gained over 20g/s as witnessed by Rowen live as we logged before and after.

Why is the power dropping off after 7500.

OMG! Is that a real question? Are you genuinely interested in knowing?
Ok I'll give you the benefit of the doubt. Do you have experience with dyno's with M cars? In Johannesburg? What about Cape Town?
Well The S54 does not peak anywhere near 8000rpm on the dyno. Up at altitude it peaks around 6900 stock and sea-level around 7200.
Why you may ask? Because a small dyno fan can not in a million years replicate the air flow one gets on the road. The cooling air flowing through the grille, spoilers, ducts and dams at 170km/h at the top of 3rd flows over all the fins of your radiators, oil coolers, etc and keeps all the fluids cool and the ECu happy. A 40km/h fan directed at a small part of your grille (and totally away from the intake scoop in the brake duct) will never keep the fluids cool and the car will peak early.
But you knew that right? You have never seen an M car peak early on the dyno right?
Just to illustrate how unhappy the cars are on a dyno, here's another E46 that we did this week. I will post the dyno run also from KAR (sorry for the cellphone pic from the owner, I wasn't there) so that you can see the sorry state of the stock run. Look at the bottom run, it peaked at 6900. And the car was stock. The ECu definitely wasn't happy with the airflow on the rollers.

darens car makes power over 8000 on the dyno.

On which dyno? A different dyno to KAR? With smaller rollers? And what about the fan? A bigger fan? I don't think it's at KAR as I was there on the dyno day. Please post the graph if it's from KAR. If it's not from KAR then it's totally irrelevent.
But hey, well done to Darren that is good. On the road Rowens car makes peak airflow at 8450rpm. But hey, we can't compare apples to oranges.

this is my 1st //m car unfortunately. I only came by the means to afford one lately. So i'm new to the //M power club but have always been a fan. I dont speak as if i know it all coz i dont but you appear to know it all from the comments u pass. You Taking on guys like XPower that have owned every generation of m3 and old toppies like Aren on the vwgti club forum so i was just curious thats all...

i dont really care how many m's xpower or aren have had.
i am sure the spanner boys at the roslyn plant will know more about m3's than any one of us.
i am also sure that a large majority of them have never owned a single m.
see where i am going with this?
i am 27 btw , do a serach on the vwgti club to see my x cars

Damn, I hope i don't create further controversy...again.
1. Firstly, the dyno reading is a true reflection of the M car with software...but it seems exede has unlock quite a bit more KW and Nm with its software and these are pretty good numbers indeed...i also think the "before" provided by Rowan even though it was on a different dyno is pretty close to the general stock numbers and therefore the increase in KW with the exede is phenomenal indeed. I have seen lower numbers on Ms with different software...so well done guys, i genuinely do mean this comment.
2. I agree with Xpower the tapering off at 7500 is expected...but Anile you must also notice on the graph that the Nm is sustained and probably well over 8000rpms. Also remember this is just a software tune. Adding an aftermarket exhaust and intake you can definitely expect higher Nm and Kw should peak 8000rpms on the dyno...but this is just a guess.
3. Rowan is right, you have to feel the power on the road and that is what matters. I am sure the car revs (up) even more frantically than before and that feeling and experience a dyno cannot show you.
