im having same prob i think, was told should b making 230bhp with engine im currently making 203bhp and 203lb/ft at 16psi so near on 30bhp less of what i expected plus its making it so late in the revs, (main concern) only make 100bhp at 4000rpm then at 4600rpm im making 185-190.

most rst graphs ive seen go sky high at 2500rpm (or there abouts) whats ur power graph like m8?

it was suggested at rr i went to that cam timing could b out, need to get it checked asap

what is it thats mentioned about belt being off by a tooth? soz i dont understand, not a mechanic!!
