nice review/thread! I just purchased my 08 335i and Put jb4 G5, vrsf cp, and stage 2 LPFP from fuel-it.

I was getting half engine light, so my buddy with his cobb put in on my car when I was stock. He told me it was the LPFP and show me while running. I replaced it, and still get half engine light. I then replaced the spark plugs and coil packs. Got the code for the Vanos cleaning everyone does. So I clean the Vanos solenoids(both) and now I am getting the coide 29DC. I will run a log tonight and and see whats up. I just got JB4 and and my CP not too long ago. Installed them both but never did a log. I think its time to do one hehe
