Hi,
I have compressor surge issues and wondering should I put an additional BOV on the hot side of the intercooler. Due to the engine being mid mount the intercooler pipework is very long. Probably almost 7M in total. Current BOV is vent to atmosphere and is around 150mm from the throttle body. It is opening and blasts your hand off on lift off but listen to the light acceleration run on the below link on lift off. Not sure if it makes a difference but it also has an open screamer pipe.

Slow pull away then around half throttle to 60mph with lift off
