Dyno with cams and headwork - 130bhp @ 6500 Note: Standard power on the 2.0 is 130!!!!

Dyno with above and:
ST manifold+cat
Magnex
vernier pullies
65mm tb
Unicip

154bhp@6500 I was expecting more, Paul form Dastek said that they could have got more power with a standard head on???
Really cannot understand this, neither can Andy from CHD.

Cams have been set up using vernier pullies, TDC guages and cam swing on dyno.



Please help!
