I am looking for some advice.
I have 2003 WRX Non STI - 3inch Turbo Back exhaust with high flow cat. Process West CAI and verso tune.

What is the next "bang for buck" power upgrade and what sort of power gains expected?

Bigger injectors?
Boost controller?

I have already done suspension mods and brake mods so looking at power upgrades at this stage.

Cheers Tim

Bigger Turbo
STI intercooler
565cc STI injectors
Re-Tune

What I did and its great

EDIT: what AJAYJAY said: Fuel Pump
