I've got identical mods to my car, Trust PEII, Pod Filter, and Apexi FMIC... also a Nistune ECU. I lost about 9rwkw on the dyno after the FMIC install, which my tuner says is because boost had dropped after installation of the additional pipework for the FMIC. Basically it's begging for more boost now. The solution was to get a boost controller or in my case a HKS adjustable actuator... the HKS actuator works an absolute treat by the way. It's now sitting pretty on 11.94psi, and feels 100% better.
