My FD runs with PFC without problems , 0.9 first turbo - 0.8 both turbos, but some times specialy with cold weather and 5 gear makes over boost . The max that i saw in my commander was 0.97 . Its necessary to buy a boost controller and if yes which is the best for PFC ?
I m running with 11.5 - 11.7 a/f ratio with 100oct fuel .

well, your fuel could handle it if you alway's run 100 octane but if you want a boost controller, just get a profec B........ thats the most common one.

100 octane RON? that's like 95 octane in the states. Even with 95 octane, I'd rather run 11.2 a/f.

There is also an PFC Boost kit/controller that is designed to work with the PowerFC. It is not widely available, in the states only SR motorsports has it. Freaking $379, part 415-A008.

Read this thread, a good discussion about boost controllers

Um... weren't a lot of people complaining about the PFC boost controller and it's ability to deal with the transistion spike?
