[corbs09]

Hey all-

Just had a few quick questions.. I saw that Terry mentioned in a thread he has customers running the JB+ with the PPK package from BMW. I have an 09 with PPK and have a JB+ I can run. I would like to know a little bit more about how the JB+ works...

Does it simply make the car run the same tune as far as A/F and timing goes just with a higher boost limit?

My car has the upgraded tune that adds I think 1psi of boost, so would it be safe to run it at 35% to get a little boost in power?

Also, my car has the PPK with 48k miles, It states the spark plugs need to be changed at 45k. Could this be causing the low rpm misfire I am getting or should I be doing something besides simply replacing the plugs prior to installing the jb+?

Thanks!
