Wow baseline numbers are great! Love the car! Hate to say it but might trade in the M for one.

What kind/brand of dyno was it? Sweet #'s for sure.

Nice choice on the wheels/tires. I'm not at all into the whole poke/stance trend either, your car looks great!

Saw my first M235i (in person) at BMW on Saturday, very cool little cars. If it wasn't snowing out I might have asked for a test drive

Great numbers! Can't wait to start modding mine. I still only have 400 miles on it.

1. Awesome job with your initial round of modifications.

2. Wheels look fantastic (and you dropped weight on each corner).

3. Damn the M235i is powerful.

Congratulations, OP.

Thanks .

I got the CEL on the way home, but I am not too worried since it'll be removed once the JB4 gets in there.

The dyno used was a DynoJet @ EAS and I plan on using them for the next round of mods to keep it more consistent.

The car is pretty quick for what it is!

Beautiful car and sweet rims. Made some good baseline power. 350ish bone stock to the crank is pretty darn impressive.

We all assumed BMW underrated these things like crazy tho anyway.

Give us the update with some install photos on the JB4 once you do it. Looking forward as I have talked to them already about the Stage 1, but might be convinced to go Stage 2 if there is a way to remove the ECU wire taps during uninstall without anything left at the scene of the crime

did you order the down pipe with additional EGT bung or O2 sensor bung?
I am thinking of doing this on my F10!

i'm with that, wheels seem a bit plain or old. the stock one's have a heck of alot of more detail and sculpting... not busy, though...


The exhaust sound, sounds fairly loud, burble and all is evident. but wish there was a much deeper overall tone to the exhaust.

I got 353whp with the following on my M135 (same engine)
Hartge ECU piggyback
AFE intake,
BCS catted downpipe
MP muffler
Wagner Competition IC

other mods which enchance stability..

Dyno done on dynojet (remove rear wheels with hub attach)
I am happy with the current performance

I believe you can get higher whp with JB4
