There is someone on this forum who does have it (search) and he's quite pleased. I'm not brave enough though

if i have been running JBplus on top of GIAC flash without any issues i dont see why it shouldnt work on top of the Performance kit.

By the way BMW has released an update of the PKit software since many complained about overboost codes and throttle closure at low rpm

JB+ works on top of the BMW performance, just don't push it too much. 50% gives you a nice boost and should be code free. Just make sure you have a BT tool to check.

cheers

Well, about 50 % is also what I had in mind. Did not know about the update; I will get my BMW PP in 2 weeks, so I hope its already the update.

I assume they will always intall the lastest version. I had some issue with starting the engine and I got the new software 2 weeks ago. But I can tell you, the power kit is already a nice bump in power, more then I expected. In Switzerland this is already more then enough to get you very fast in a lot of troubles

Sounds great!
I guess, our 100 octane ROZ fuel (~95 Ron) also helps the BMW PP a little bit...

How does the new software feel ? Same as the original ? Any changes ? I will install some electrical module on Tuesday and I will ask for an update too...but to be honest the current version works perfect for me. Throttle closure at low RPM...maybe.
