The ecoboost makes all kinds of noise you just didnt hear it with the stock air box and filter. its perfectly normal. and no amount of pre turbo mods are going to make any differance in the boost leval or fuel mixture on the EB engine it is is controled 100% by the ECM. If you want a tune or exhaust go for it you dont need an excuse. But if you play be prepared to pay.
