yeah that sounds about right! i never had any real problems with cops, they ask me if i have a bov i say yes, but it's the standard plum back put onto the ic pipe, which is true btw! i have no turbo timers, guages or anything in the cabin besides the hand controller which is under a pile of stuff in the glove box! car isn't loud so they've never really wanted to waste anytime trying to find a defect on my car! generally let me go but before when my car was fully kitted up with bling all over the place under the bonnet they wasted time looking for defects!
