My Ride: Whiiiite BMW!
Iceman- any idea why my car is tapering off rapidly above 6k? I know it should flatten out but that result is a bit odd in my otherwise typical power band. I have the run files if they help.

I wouldn't be able to tell from that, but it looks like it's pulling ignition timing, probably the knock sensors hearing too much "noise." I would flash to stock and get the newest software update from the dealer and then load my shark back on.

Edit. Looked at the wrong dyno, actually yours looks fairly healthy.

Here it is "raw". Isn't the sudden drop at 6k unusual? I thought it was supposed to taper.

Dyno type: Dynojet
Peak numbers:195 whp/ 187 wtq

Dyno runs are with Epic tune and after un-flashing Epic Tune
Don't read into this too much yet, other factors may be at play like my restricted exhaust and the fact that residual adaptations from the Epic tune may have been still there after un-flashing it. Last dyno with the same mods, in albeit in different conditions showed a best run of 188 whp.

Run 5 with, Run 10 withoutv

FYI: Car baselined at around 304HP w/full bolt-ons and a tune on the very same dyno. The dyno is calibrated to approximate Dynojet numbers, although it does read slightly lower than most Dynojets in the area.

Is that with the EPIC Alpha N tune? That would explain the csl airbox...

Do you have a number on how power that airbox gained?
