Thanks for that Craig, I didn't realise they detected engine vacume. I thought they just went on intake pressure.

On Garrett's setup the blower blows through the MAF sensor whigh is almost directly before the throttle body. I've been thinking that removing the MAF and geting a MAP tune done would unleash a bit more power. I could also put the BOV on the tube section that will replace the MAF but unfortunately this is after the intercooler. What's the reason for having the BOV closer to the blower on a blown car and the other way on a turbo?

Cheers
