Why would you do that? Same tuners will have a tune for the 335 that will literally leave their own chipped 328 in the dust. And just because it's a 4-banger don't mean it will get killer gas mileage. The worst gas mileage I've ever experienced on any of my cars was on a modified 4-banger: try 8-10 mpg when driven hard. I have to drive like a granny to achieve 23-24 mpg on my stock '12 GTI, and this is one of the most efficient turbocharged engines out there.
