air box ( airraid on a turbo gt) what amount of hp gain would i see, and would i lose low end etc...

exhaust ( gt turbo), the factory exhaust is suppose to be a flow through design, what would i gain from installing an aftermarket exhaust? ( btg, borla etc...) and hp gains?

stage 1, hp gains on a stock gt? ( and does it efeect everyday driving, eg to work, highway use etc...)

strut tower brace (on a gt) would this be a worth while investment?

BOV (gt again) doesn't increase HP, so why do we need one?

does the ecu, need to be reset with each mod, or will it learn on it's own?

thanks
