I have been running the Mission Performance Stage 2 tune for the last two weeks.
I’ve been happy with the drivability, drives like stock but just with more everywhere and much more up top when I’ve had the chance to wind it out.
Finally got a chance to get the car on the dyno this week and the results were better than I expected.
The car has the stock intake with a K&N filter and stock downpipe. Running Australian 98ron fuel which is similar to US 93.
It's worth mentioning up front that Australian dynos usually read lower than US spec Dynojets. Although most Australians have commented that my baseline seems high.
Also worth mentioning that the M140i stock tune is 250kw/355hp similar to a 340i with the performance Power kit.
We did three power runs with tune loaded and all were very consistent around 390whp, best was 391.8whp.
Flashed it back to stock while still strapped down and did three runs, once again all very consistent around 300whp.
So approximately 30% gain with just the tune.
The Mission Performance tune also runs safer AFRs than the stock tune which stay around 14-15:1 the whole way.
We couldn’t find somewhere to tap into to get a boost reading, but going off my P3 ODB gauge it looks like peak boost went from 12 to 18psi.
I’ve ordered a BCS high flow catted downpipe to help it breathe a bit better. So will go back once that is on and I’m expecting over 400whp.
For comparison two 1Ms were on the same dyno a couple of days ago and with intake, DPs, intercooler and MHD stage 2 tunes they both were around 350whp.
Overall I wouldn't hesitate to recommend Mission Performance. The process was simple you just need a laptop, his software, an internet connection and an enet cable. Or it can be done in person if you are located in California.
