Something sounds wrong to me.  These readings are high for a turbo with a 
stock camshaft.  They should be more like 130 PSI.  High readings can be caused 
by a mild cam, carbon in the cylinders, or mismatched parts.  It's also 
possible that a worn camshaft could cause the readings to be high due to less overlap 
in the intake/exhaust valve timing .

(Compression readings from 180 Turbo)
1 - 12 bar = 174 psi
2 - 9,5  bar = 138 psi
3 - 11 bar  = 160 psi
4 - 10 bar = 145 psi
5 - 11  bar = 160 psi
6 - 10 bar = 145 psi

Hope this  helps. Regards, Guus de Haan <unsnip>
