ok, i think we concluded that you need a manual tranny, and this post might be long forgotten, but wanna turbocharge my n42 too and i have a manual tranny =D. Is there anything else i should be considering? I don't remember exactly where, but i saw a guy saying that he pulled 290+ bhp out of his n42. how would i do that?

Hi,

This is very interesting thread, I never heard N42 with turbo installed.

As we now that N42 basically natural aspirated which require vacuum to control the fuel supply, valvetronic, etc

i think turbo has been screw up the maf sensor or either pressure sensor, this due to loss of vacuum which require to extend the fuel supply and let valvetronic adjust the correct angle.

These error is linked to tranny via can bus, resulting in transmission error.
