This may sound silly but my car doesn't physically feel like its lost any power, it's still seems to kick and zoom like it always has but recently I've noticed some cars normal run of the mill type cars, nissans etc actually catching up on me where as in the past it would zoom way ahead.. I know there is a lot of specifics involved but I feel like twice in the past week while pushing it 2 normal cars caught up with me whereas that never happened before.. if I pushed a little more it used to zoom way ahead..
unless these cars where hiding some magic under the hood but I highly doubt it..
am am I just crazy and paranoid? I know I don need to get a new aux pump soon, im still trying to convince my indie to do the upgrade Bosch conversion big will posted.. 😂.

Could it be my supercharger is not working? I just went out again and met some friendly guys in an m3 we hit some side streets, they killed me.. It was a stock 3 day old m3, ive killed tuned m3 and m6s not long ago, and no i have nissans coming up on me something is wrong.. the intitial take off seems ok, but theres a loss of power somewhere?

Im not so sure, ive killed brand new m4s and m6s with my XFR along with suped up mustangs and camaros.. it was a stock camaro the first car i noticed being able to catch on, then an altima, then some old *** bmw.. its really strange... The best way i can describe it at this time is..
Up to 70-100mph feels normal enough but the quick zoom when pressing the gas when cruising at those speeds has gone.. It would quickly push when putting the foot down slightly now theres what i can only call a lag, i hear the rev go up but takes a little charge before pushing..
Does that make sense to anyone?

a 2017 M3 is going to be equal or slight edge to a tuned 5.0 supercharged xf...or xfr as well same output..... you might have something not quite right... im tuned with pulley and pull about everything that wants to go...its usually just the cars that think they are fast that usually wanna run... the WRX s regular BMWs and Audi's

I have no idea what this means lol, sorry
Is this the big manifold when u open the hood that goes left and right? If so mine is brand new, only replaced that a few months ago?

Yep, literally thousands of codes can be generated without causing a CEL, a good/proper code reader will show most of them, although to see all of them in detail you need the proper SDD equipment.
I use an iCarsoft i930, picks up almost everything, see here: iCarsoft -Professional Multi System Scanner For LandRover / Jaguar / OBDII -i930 | eBay

No, it's the actual intake valves. Deposits build up on them slowly as you put more miles on the car. So it's a slow effect of robbing power so you won't notice it since you drive the car every day.
You need to remove the intake manifold and clean them off. It's a very baked on tar-like substance, and I found it's best to use throttle body cleaner by letting it soak the valves and then scrub gently with a firm brush.
Not a fun job, but that's the downside of direct injection. You can google it to learn more.
I did it on my gray XF and it made a big difference in power.
