i have a 01 GT and i just got a FMIC for free i was wondering if it would be better or worse with it put on.. i am running 10 PSi but wouldn't routing it all over the front of the car and sending it through the FMIC and the back up to the intake have a negative effect an make me drop PSI??

 

You will for sure have a pressure drop. Depending on how much of a drop will decide on whether it's worth the install.
