Incorrect. The Q45 utilizes the throttle body and coolant temperature for fast idle. The RB25 utilizes the air regulator for fast idle. So you want to remove the fast idle system from the Q45 throttle body when you use it with the greddy intake manifold.

I posted that information before. I use the greddy intake manifold with the Q45 throttle body. You do flip it upside down. I'll post some pictures for you.
