I have R888s and love them. They hook well. Noise isn’t that bad…..IMO.

I run 888 too, and I can't hear the whine when my windows are up. I've run 3R, 4S, NT05, ET Street, and now 888 and these are best on dry surfaces. They all suck in the wet, but 4S is best.

I had difficulties carrying a conversation with my wife in the car when running these Toyos, even cruising, whenever the road surface was anything short of brand new blacktop.

Good info, thanks. I manually hacked, pardon, "overlaid" my curves onto your dyno sheet just as a rough ballpark reference comparison (yes, I have a tiny torque dip near the top).
Neither the runflats nor the PS4S are likely to hook up from zero, but the PS4S at a slightly lowered pressure will work from a much slower roll. It'd be interesting to find out exactly how low you can go with the starting speed, but of course you'll need those tires and then some guinea pigging willingness

Thanks, I'll be here waiting for the dragy screenshots.

Surprisingly the car hooks in 2nd gear... And damn is it fast! Still need to get dragy data as I threw a check engine light on the way home and they're sending me a revised tune.

Awesome, great to hear -150 rwhp does have some advantages

Yes, my car is an A8 (tuned). What I typically do is blip the throttle to the floor, which engages performance shift mode, the A8 downshifts to the optimal gear for max torque at that speed, rpms climb to 3500-4000, and then I floor it for some bam-bam straight line shift action.

What does your actual dyno sheet look like? Because this one being 46 mph to 142 mph, in an M6 car with different gear ratios than your A8 car, and with different tires than yours as well, means that your drawing is very much apples to oranges, in other words, bogus. Would need RPM-based graphs from both in order to pretend-overlay like you did. Yes I am pointing out that even if your dyno operator screwed up like this one, and gave you a speed-based dyno sheet instead of the correct rpm-based, the fact that your gearing does not match his would invalidate a straight comparison of mph vs power.
