What other setup do you have?
Oversized valves?
Manifold(s), turbo, IC??

Bog stock?

Car is basically standard, apart from sweeping downpipe, k and n filter with drilled airbox, 'chipped' ecu, and manual boost controller, turbo and ic are standard items. thanks

Oh really, how do you do it? only way ive ever done it is by compressing the spring (with valve spring compressor) by holding the valve 'head' and releasing the colletts, thanks seb
