fuel pump change. retune necesary??
I got a single turbo set up on my FD, I'm running a supra fuel pump with the areomotive regulator. If I have a good tune with my PFC with my current setup and later decide to change my fuel pump to a bosch should I get the car retuned or will it not make much of a difference as long as I maintain the same fuel pressure at idle?
thanks!

Unless your base fuel pressure has changed... Negative Ghost-Rider!
