Hi there, I bought my E91 335i with a DMS remap already done. The car made 368bhp with this.
Since I bought the car I have fitted BMS dual cone filters, VRSF downpipes and VRSF 7" intercooler.
I had the car on the rolling road yesterday after getting the downpipes and FMIC fitted, it made 394bhp.

What I wanted to know is, should I be getting the map tweaked by DMS again to suit?

I have even considered getting the jb4, this actually works out a good bit cheaper than getting the DMS map done again too. Would it just be a case of wiping the original DMS remap and installing the jb4? I don't know too much about the jb4, seems to have a lot of features though.

Finally, does anyone here run the BMS meth kit? This is another reason I was interested in possibly getting the jb4.
