I am looking at purchasing an apexi power FC with the commander. Here are the mods I got right now:
Bonez downpipe
high flow cat
racing beat exhaust
pettit air intake
manual boost contoller
aluminum AST
boost gauge and temp gauge
I got a flidyne radiator coming

So I am wondering what fuel mods I would need with the power FC. The car is a daily driven street car. Am i ready for bigger injectores and a walbro?

Also with the PFC do i need a boost controller or does it handle that?

 

There may be more info in the PFC section of the forum.

Fuel is relative to boost level, and without an upgraded intercooler I am not certain what boost level you will be running.

There are differing views on whether fuel upgrades are needed up to 15
psi or so. Some do not like to run over 85% injector duty cycles.

The PFC does control boost, some individuals have success using it others have not.

Here are some numbers from an old log, at approximately 13 psi, 11.6 AFRs, and 7,2xx rpms my duty cycles were about 87%.
