Thanks for the welcomes.

Having a few issues with the car Previous owner told me it was mapped and running 350bhp.

Its got a chav valve (im thinking this maybe causing the issue)

when in high gear on full chatter the engine splutters when on boost. sometimes it sounds like the bov is opening when boosts initially kicks in. Its a collins one.
Also i get no traction what so ever. the power is just wasted eating the front tyres, any suggestions?

Thank you
