for the most part, probably yes. but you should really put an EGT gauge on it. you risk blowing / melting the turbo with poorly manages over fueling on stock components. Also a tune will sort it out very easily.
you cant just swap the nozzles DIY. well you can but its very risky. most have issues with doing this as you cant pop test and tune them DIY. you have to send them out and for the cost, totally worth it.
we need to know, what year your passat it, and what the parts are coming out of. we cant read minds.
