    Default Stage 2 but below standard

    Have a stage 2 turbo hybrid, full decat 3inch cobra exhaust, forge induction kit, breather hose, boost pipes, dump valve, turbosmart recirc, and forge actuator plus stage 2 remap.

    Just got it off the dyno but states 236bhp how is that possible? Had 5 sensors replaced as a rule out but still same problem. Anyone have an idea?

    That is weird

    1st thing I would start with is a compression test to rule out worn rings or a knackered valve seat etc

    But the dump valve might not help in all honesty I'm surprised a few certain members have not burned you at the stake for even mentioning that word

    Tbh vxr online is a bit of an anti dumpvalve bunch

    I nearly bought one myself few weeks till I was convinced otherwise

    Having said that even a dump valve shouldn't be robbing that much power

    Im removing it all tomorrow, also if a turbosmart recirc isnt fitted properly ie: not in the groove etc would that play a part? As im starting to wonder if thats actually in correctly.

    There's rhyme and reason for it.

    Not seen a single vxr run right on an oe /hybrid turbo setup with a DV
