so i have the 1.4 turbo and i want to purchase a bov but i cant find any. need some help if possiable.

 

The only point is getting a BOV would be if you want some whistle and it would indeed require a different ECU tune to have the AF mixture right.

BUT.................


Just about any performance intake is going to give you some wastegate and blow off sounds at high RPM's and you'll get more turbo whistle too.
