I've not had time to add mine yet but have just changed my PH profile picture to show dyno plot from earlier this month.
Unmodified 73K mile car ( new Vanos at 60K ) gave 299 prior to mods at Evolve. ( Simota induction, Supersprint Cat back and new map ).

Sorry to hijack, but whilst I have Vixpy's attention...
Vix, this MAF eating problem you've experianced with the DaveF K&K kit on the RR, what are the symptoms. My inde'says the car is overfueling, causing a very lumpy idle. He can't reset the idle settings, so I booked it in at the dealership (Cha-ching). He did find a badly perished crank case breather hose, but after replacing, it's still as bad as it ever was. Strong as 'ote above 2K.
Could it be related to the MAF quoffing DaveF?

Hmm.. The maf issue tend to cause problems with under fueling, not overfueling, but if its on the way out the ecu's do sometimes do silly things with the fueling.Vix, this MAF eating problem you've experianced with the DaveF K&K kit on the RR, what are the symptoms.

I'd take the maf out, give it a clean and see if it improves.

Confused again ~ Please can someone explain. I dont understand why there are such large variations between RR results. If Wheel HP is the "true" power being generated how do Powerstation's losses generate 333 at fly from 236 RWHP but other RR (Dyno Dynamics) show 263 RWHP = 316 flywheel HP ( ie RWHP + 17% for 2WD ) Dave.

Just different dyno's chap, and different ways of extrapolating flywheel figs.Gassing Station | M Power | Top of Page | What's New | My Stuff
