hi my car only has a kakimoto cat back at the moment, looking to get a DP and MP for it ,but have been told to get apexi PFC fitted at the same time ? wot sort of power will this put down? also how high can i go with the boost on this set up? (currently 10-8-10 psi)

also as im so far away from RX7 tuners can i send my apexi PFC down to REworks or drangon or that and tell them wot mods i have n they can put a map on it for me? well atleast so i could drive down n get it mapped by them.

thanks.

 

You're not going to gain a great amount of power with those mods. But it's a good starting point. I'd stay away from the MP for awhile, it can potentially do more damage than good with your setup.

Stick with 10psi, you don't have the supporting mods to go any higher. As far as the PFC goes, you'll be okay with the base mod map. But get an intake.

 

i got an hks drop in filter or wil that need changed?
