Should I installed/tuned PFC first then install catback or could safety install catback then install/tune PFC.

Current mods: Apexi intakes, HKS downpipe, Greddy SMIC. No boost creep.

TIA

 

Get PFC it will make a world of difference!
Then CB

 

Already bought the PFC. Catback is coming after the Holidays.

So I can installed PFC and have it professionally tuned then install the CB and the fuel map would be still good...is that correct?

 

The exhaust wont make a huge difference, EXCEPT, that you may start getting boost creep, which isnt too much of an issue IF the PFC is tuned for it, ie I'd get a boost controller of some sort <maybe a couple home depot/hallman type units> and raise the boost up to 12-13 psi when its tuned that way if it starts creeping with the exhaust its already tuned for it.

 

Yes. 12 psi was my plan...otherwise wouldn't have bought the SMIC. Tunning I am not gonna mess around with...taking the car to Gothamracing after new year.

 

the pfc base map should handle your mods (with CB) just fine. i'd want it tuned after the CB install just to get the best results possible. steve kan is at gotham right? if he's tuning the car, ask him.

 

With the intercooler the intake and the downpipe I think you are going to start getting lean. If you can swing it your best bet would be to put on the catback and the power fc. That way steve can tune the car for the setup you are going to have and there won't be any question of the fuel mixture getting leaner or the boost getting higher than wanted. With that stuff in place your boost will probably come up to 12 pounds with the stock ecu. The fc can control the boost fine by itself and I don't think you will get any creep with the catalyst in the system.

 

i dont know if you have one but if not, you should also consider a fuel pump.

 

yes I am. Probably will have it installed at same time with CB & PFC.

 

make the changes (cat back etc) before tuning or else you'll need to re-tune. you should be fine with the base map, but since you are so close to Steve Kan at Gotham Racing i'd go ahead and give him a call and get tuned.

i'd probably say that you don't need a fuel pump until you start flowing more air (more mods such as midpipe, intake and intercooler) and making more boost and at that point you would probably want bigger injectors too.

tuning is probably the most important step of modding a turbo rotary. very few people know how to do it right and when it gets done wrong, the car runs like **** and the engine will not last as long.
