Genuine BMW M Performance Power Kit

Viking.dk · 04-04-2020, 03:35 PM

Bought my car recently. I thought it had 326hp with the original installed M Performance Power Kit. After installing BMW M PERFORMANCE DRIVE ANALYSER, I see it's running 17,4 psi at maximum boost.
Anybody know how much psi the power kit gives max?
By the way. Car is bone stock

17.4 is high for stock turbos, so probably about that. High limit on stockers is 19, 20-21 PSI.

Ah, you might have pulled 17psi on a shift, but thats nowhere near the target. More like 12.5 max.

Yeah it's too much psi for M Performance Power Kit I think. BMW would never run so high, when you think of they have to give warranties on the engine.

Hmm. Full throttle and my gauge shows this: [IMG][/IMG]

Your car is definitely not on a PPK map.
PPK map targets around 12psi.
The previous owner must've flashed it with something else.

Yeah, that's my thoughts too. Just need to get confirmation. Thank you. I will get it for a dyno after lock down period is over.
Bit disappointing when you think you have 326 hp on the engine. And you think it's feel quick, and look forward to FBO, and a flash. To raise hp.
Now there is not much gain on FBO. Right?

Lamda of 1.05 at full throttle is kinda lean, rpm is missing tho so not sure. Just for you to chk are the psi units gage or absolute?
Also it says manifold pressure which is not a measured quantity (sensor in the cp measures boost). I remember with the torque app it capped manifold absolute pressure at 17psi or so....(limitation).
If the 17.4 number seems to be a hard cap and doesnt go above it no matter what, then it is a sensor limit (absolute pressure)

8 degree timing is a giveaway. Won't be that high unless the revs are way up and then stock turbos will really struggle producing that much pressure.

FYI Rpm was low. Around 2000 rpm

Yep, that's absolute pressure then 17.4psi, actual boost is may be 2.7psi (depending on your atmospheric pr)...
Edit, lol i meant sensor limited to 2.7psi

Thanks for your help. What app are you all using to measure boost correct?

Also have a ppk on mine and after I flashed mhd it actually felt like I lost power after stage 2+. Maybe just all in my head tho
