on that point i failed to mention my aftermarket BOV was on the intercooler to plenum corssover pipe not on the plenum crossover pipe (not me, came from japan like that) and the instructions said the box should contain 4 pipes for RB20/25, etc but there were 3 and 2 silicon joiners when the instructions said 3. ill get a pic of the engine bay to shou the end result. Being a Sunday there obviously wont open.
But in saying all that the performance has improved quite a bit.
