No question a chipped 2.0T will be a cheap performance bargain, but a 2.0T +$500 bucks will definitely not equate to a stock 335i.
I would bet there isn't a whole lot of room on the table for performance with this engine. The gains would probably come from reducing back-pressure, improved intercooling, and possibly a less restrictive intake and a tune to accomidate these improvements. I'm 90% sure you wouldnt see the same percentage level of improvement as the N54 per mod.
