Okay so my sister bought a 06 mustang with a FRPP intake manifold and the car is not tuned for it so it throws a check engine light on. I told her if I help her get the car that she would have to give the intake manifold and I'll just put my stock intake manifold and stock plates on her car so I can clear the code. But I was wondering if there is a benefit to run a FRPP intake manifold vs stock manifold with delete plates on my car now. What do you guys think? Should I buy another stock intake manifold and keep my delete plates on and sell the FRPP intake manifold Or just run the Ford Racing intake manifold and sell the delete plates?
