What mods has it got ?,as that's quite a loss, what are you basing 30 bhp loss on ?

got an akra end can..evo airbox ..got a chip set for those but even when tried with standard chip it was still the same..guy said it was losing that much power at the top end..93 brake was top measurement..compression test was ok.

when it went on the dyno exactly how far out was it out buddy??
the dyno guy will be able to give you the answers to this if your cannot deciper the graph he gave you.

The reason i ask this is that if your expecting 125 BHP outof a small valve rsv engine then im not sure your gonna get it without some heavy mods!
