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

PFC first.

TX PFC vs. Intake

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.
