There are a lot of DD shops that won't turn up the 6V92TA DDEC power past 270 if you have a transit code in your DDEC. You have to fool the program and most shops won't do it because they are scared of fines from the EPA.
Yours being 330 hp it will have the 4775 injectors already and it should have 7512 turbo all it takes is programing 300 bucks at Pittsburgh Power if you have the 7511 turbo the housing will need to be changed to reach 400 hp
Watch Bruce he likes HP you may leave there with a 500 hp 6V92 lol just kidding
good luck
