VDI Woes

I recently put my car on the dyno so that I could do some data logs. I found something very disturbing...major power loss after 7250 rpms.

For those who do not know that the VDI valve is; it is a valve that opens around ~7250 rpms and it allows for increased airflow into the engine.

In order to inspect that pesky valve, I ripped my upper intake manifold off (which is a royal pain by the way):

If you want to do this on your own please please please make note of where each fuel line clips goes. I did not do so and I installed them improperly as seen here:
