HKS EVC IV or Greddy Profec B Spec II

I`v used the evc iv 3 years now, never needed to upgrade.. yet ;)

 

Don`t understand what you mean by gain... but you can set either single setting for pressure OR low pressure (low rpm) and high pressure (max rpm) and box calculates values between them (for example with single turbo, reduce max torque when single turbo comes alive... a bit safer car ;) ) There is also scramble boost button for instant higher boost setting. Only thing i miss would be controlling pressure settings manually by rpm points, new units (evc 5 etc) have this function...

Cheers fella's

Opted for the Greddy in the end! Looking at reviews and stuff on the web it seems to be a lot simpler to operate!!

Had a look at the EVC V but wasn't keen on the big display!!

 

You're missing out bigtime if the EVC V was a viable option. It blows most boost controllers out of the water.
