Hi there folks,

Here is my 2016 440i X-Drive Gran Coupé with MPPSK after tune by BR-Performance.

Base power is 360HP/500NM and after the tune I was happily surprised to see the gains of around 100HP and 100NM, with power now 463HP and 608NM.

Besides MPPSK and tune I have Eventuri intake, CG-Precision DS1 downpipe and Wagner Tuning Radiator (not that this last one make any difference on Power anyway).

I think this shows very well the tune potential of the B58 engine ! S58 tune will be pretty brutal when it's out...

Planned next are Pure Turbos Stage 2 and ultimately BMS meth kit when car will be out of warranty.

Here are pictures of today's re-programmation, everything looks very good except maybe a small glitch around 5800/5850RPM :

Nice gain. Did you het this done in The Netherlands or Belgium? What kind of fuel did you use?

Neither, it was BR-Performance in Nice but the tuning map is done remotely by BR Boss in Belgium. Fuel is Total Excellium 98.

I was myself surprised by the gains ! With my downpipe and intake it was supposed to be 420HP/620NM, so surprised by HP gain but a bit disappointed with torque.

Now, I wonder how Pure S2 would heighten that.. At least 480HP ? More than 500 maybe ?

Overall, car is much smoother, pulls harder and even ECO Pro mode behave better, for example, when going up from underground parking lot. Done is some stuttering I had in ECO Pro.

Weather was rainy yesterday and this weekend is mostly family time but I will report here when I have more time to test it.

Thanks, looking for a tune to replace my jb4,when I am out of warranty, this looks great!

I think the PS2 Will need extra fuel to use Its full ability. However I think if you would add meth you would probably gain another 30hp Which would make it close to 500bhp (on the dyno you used) with the standard turbo.

Yes, BR-Performance is a trustful company, you can go for it.

It's probably wiser to wait for upgraded fuel pump before modifying turbo yes.

Also, meth+JB4 will make me able to control parameters more finely and adjust to bigger turbo and water/meth injection. This could probably lead with adding close to an other 100 of HP and torque.
