Does Boost Controller really make a difference?

Right on..:)

 

didn't EVC know it's can be programmed to rev specific...but over 1bar wouldn't CEL occur? SO many horror stories and seems our ECU very hard to crack.

 

If you're using EVC, better to tune with piggyback ECU like EManage Ultimate to "defeat" the CEL. The CANBUS system is damn sensitive and will always CEL to protect engine when it detects overboosting or too much airflow thru the MAF.

 

So far only once CEL since I changed from Unichip to EManage Ultimate. In the process, EManage Ultimate gave me +30bhp and +30Nm over Unichip. Hardware remained constant, so by merely swapping and tuning of different piggyback gave so much difference... :)
