Can some people tell me what is some smaller things I can do to gain more power ive already did few things like afe cold air an ppe boost valve is there some more things I'm missing? Info would be great thanks

 

I would get a custom EFI Live tune.

but before jumping on the HP bandwagon i would look at a larger exhaust for lowering exhaust temps and helping out the turbo and getting a set of gauges so you know how hard you can push it before the danger zone.
