fitting a Forge FMIC is worth every penny
its not about having massive BHP increases, but what the Forge FMIC does is greatly reduce the intake temperatures, therefore allowing for boost to be held alot longer and the peak figures to be alot higher. Basically heat soak is greatly minimised to the turbo, allowing power to be held almost to the redline, as with the standard IC, it simply cant cope with the power and creates too much heat
since you already have quite a few mods, a Forge FMIC would compliment them nicely
my recommendation - go any get one!
