2017 MPPSK plus JB Plus

So I bought my car pre-owned about two years ago and I had the dealership install the MPPSK kit on it.

I love how it sounds and it has awesome power.

But I decided to pick up a JB+ used on eBay for cheap and holy crap what a difference.

I've read that people have had issues stacking them together with the transmission but maybe it's better on the G30 because they put in a different torque converter for the kit?

I don't know - but if you have the kit, still CPO warranties and aren't ready to do a flash tune - I recommend it.

I will update once I get more miles on it.

Oh darn. I misread. I thought you meant the JB plus.

Let me pull up the invoice. Hang on!

Holy crap.. this is the exact thread I've been looking for - and it's on the top of the list

I was just about to email Burger Motorsports to check how their JB goes on top of the MPPSK.

Is this the kit you got >?https://burgertuning.com/collections...oducts/b58-jb4

No sir. This:

It's crazy. Took my coworker out today, we did like 4 launches in a row and it's crazy fast now.

I know it's all relative, but it's faster than just having the mppsk by itself.

I have a Dinan elite kit and it made more of a performance improvement than the MPPSK upgrade, So I expect same on JB. Btw I am selling my Dinan for 40 B58 with MPPSK if anyone is interested. (Shameless plug)

I'm looking to go with a bootmod3 tune once the warranty is over.

In the meantime this 100 dollars adds a great punch to the MPPSK upgrade.

Yea thanks.. I'm in exactly same boat. Warranty is up next year and if I end up hanging onto the car, it's likely going to get Bootmod upgrade. I mean the 540i MPPSK is quick enough already for our nanny state speeding laws here, but was eyeing off the full JB4 to give a bit more punch. The JB plus could be another good option given your experience.

We already have the burbles and mappings needed to take advantage of the extra horsepower with the MPPSK. For about 100 bucks this really wakes up the power from a dead stop. Ive seen dynos posted that show it provides only small increases at higher RPMs.

But my commute is short and the extra boost from a red light is exactly what I was looking for.

I wouldn't buy this new - keep an eye out on eBay like I did and you should be able to get it for close to 100-130.

And as far as that other thread about the intake pipe - I will probably wait for the tune. There's a strong chance I will keep my car past the cpo warranty because the low mileage I put in it. Just barely breaking 18k on it right now. I drive about 4 to 5 k a year.

Fun times huh?
