You gotta attach the MSQ file for your tune, a datalog can help too. Otherwise, you'll either get ignored or flamed by the experienced guys on here haha.

If you post your tune/settings/log etc. and are very detailed with your questions, the guys on this forum can be very helpful.

I personally don't have any useful input on VVT settings. Just one newb trying to help another.

This is a good starting point.

You can also flatten out your table a bit to smooth out slow speed driving and make it not active when cold.
