Which boost controller is better the manual turbo xs. Or the greddy profec b 2? I hear that electronics like to fail and that turbo xs is better but im still not sure?

 

greddy profec type-s, keep it simple you don't want to dig through menus. EBC>MBC imo.

 

Even though that MBC is a lot easier to use and set, You will love the convenience of switching from high to low boost in car with the Greddy Profec. The ebc's are a little tricky to set, but once they are set, their is nothing better.
