I had a 30-minute conversation with Rob (Needswings) at the race track about two months ago regarding the injectors, and he simply said not to fool with it on the N/A machines.

Aside from the power loss, there is an issue with the idle/drivability during normal loads.

This car is an enigma in several areas, injectors being one of them. This is the only car I've seen that doesn't respond well to an increase in injector flow-rate.
