Hey guys i have heard alot of shops and people tell me that changing you ECU is the first thing you should do before getting a intake. What would you go with first intake or PFC

 

What car are you talking about?

 

A 94 rx7

 

sorry i forgot to say

 

Id say the pfc, its pretty much the foundation to build on.

 

+1
get that out of the way and you won't have to worry about it anymore.

 

Cool thanks. do you guys no any places in Washington that can install it?

 

i would say exhaust first

 

Not on an FD. Get the PFC.

 

Many FDs get blown by adding intake & exhaust before fuel & fuel control.

PFC first.

 

I did intake & exhaust before the PowerFC. However, if I were to do it over again I would have purchased the PowerFC long before doing any other optional work on my '93 RX-7 Touring. Moving from the stock ECU to the PowerFC completely removed the 3000 rpm hesitation that my car had, and it made the drivability feel much more refined. I felt like it made the car drive as if it were much newer. It really made me enjoy driving the RX-7 much more.

I expect the downside of doing the PowerFC first would be that once it is tuned, you may need to get it retuned as you do the other modifications later. But I would still recommend the PowerFC first.
