Hello ! i write from Italy. sorry for the poor english. I'm interested in a jb4 for my z4 35i year 2009 automatic transmission. I have the mambakit turbo upgrade kit, direct intake with double front cone, ********, increased intercooler, charge pipe and turbo silicon tubes. do you have experience in this regard? can you configure a good 550 hp power step? can you help me? thank you very much for the availability

Ciao, the JB4 N54 Hybrid Turbo Setup Directions page gives you start up settings on the very first page. Do that, then log, then post log on the support page.
