If boost or vacuum gave a useful proxy for "how hard it's working" then that would fuel my interest in a P3 gauge. It does look pretty slick in that vent port.
As a former Mazdaspeed6 owner I was always wary of boosting at low RPM, like anything under 3000 was a no-no as there was reduced oil pressure so why BMW programmed this high gear low RPM scenario is beyond me. I'm constantly shifting down on hills to accommodate this, the paddles help.

The N55 has a variable displacement oil pump (so do the N54 and N51/52) which can pump just as much oil at 1500rpm as it is at 7000rpm if needed. Plus, the motor was designed and built for these situations (hence the tiny turbo that does after 5k RPM) and for much more careless owners and drivers. Doesn't mean that what you're doing is bad, but it does mean you shouldn't worry so much; enjoy the car!

Correct they engineered the car to spool up fast, you're actually safer sub 3000rpm than above 5500 where the fuel pumps start to lose steam.

I'm working on extending my driving season. Saving up for a summer set of wheels and tires, MPSC2, relegating the current MPSS set-up to "three-season" duty. California Love. F' the haters.

Got the call from the dealer that my recent issue was, as I assumed, a bad water pump/thermometer.

Wow, my car is being quite stereotypical and all the famous things are failing. I’m at 43K miles, and, in the last year I’ve replaced my charge pipe, OFHG and water pump. I should have them put in a new HPFP, just to be safe. lol At least I got my money’s worth out of my extended warranty in only a year.

That's one of the many nice things I like about living in SoCal; summer tires all year long.

I may get a set of Nokian WR G4s to throw on the stock 207Ms for those 1 or 2 weeks a year during the holidays when I drive up to Washington to visit my folks, though.

My daughter has a Tahoe that I borrow for occasions like that when the summer tires just won't do.

So, every other weekend or so I give the tires a feel just to be sure nothing is horribly amiss. For some time now I've been telling myself the inside edge couldn't be that bad.... Last weekend while checking out my boost leak I had the opportunity to get close and personal with the inner edges of my front tires.

Yeah, the toe is whacked like kicking a table leg in the middle of the night...

So, gonna run a string and get a measurement this weekend.

Starting a pool- pick your number, I'll post what I find and let's see who's closest... Zero (0) total toe is my target good number, I'm really curious just how far off it is.

Dinan Camber Plates and Eibach springs, along with 10 years of no alignment.

Yeah, that's why I'd struggle with only summer tires. I could almost get away with it if I only stayed around Portland, but I like taking my car into the mountains too much, and it falls below 40 degrees pretty quickly up there.

I used to only run summers when I lived in LA, but I think I'd probably run A/S 3+ tires part of there year there now, too, because of mountain driving.

Have you ever run the Conti DWS? Curious how the two compare

Hi. The only other ultra high performance all-season tires I've run are Yokohama Advan A/S on my 911, and, while I don't notice much difference in terms of bad weather traction, the Michelins are better in the dry (likely the case vs. the Contis, too.) The turn-in on the Advans wasn't nearly as good, although they were a bit quieter and cushier, IIRC.

It's really just a matter of priorities. The Michelins are at the farthest performance end for all-seasons and are the closest thing to summers, even beating out some summer tires in the dry, so they're going to be stiffer and noisier than the other all-seasons. I admittedly often forget they're not summers when driving, and I'd probably just run them all year if it wasn't for going to the track. Heck, they'd probably perform beyond my ability at the track, but I'd worry that chunking would eat through them quickly. They last much longer than summers on the street, though.
