You dont need o lower the compression ration unless your running big power, stock internalls are fine for 350bhp+ | |

could this suggestion be the prob, that the engine simply dose'nt have adaquete compression. Would def explain the big loss of power. | |

quote: There's no point in fitting a thicker head gasket unless you are winding up the boost presure. In fact your proberly losing power rite now rununing on std boost with low compression. The idea in lowering compression is that you can run with more boost, if you have'nt got increased boost your lossing power. | |

what gearbox are you running? i had a problem with the F20 that the 1st gear sensor usually in the F28 was telling the ECU it was in 1st all the time cos it wasnt plugged in and limiting boost to 4psi and only 189bhp. | |

the mods youve done wont increase or decrease power,if its not performing like it should give it a service if thats not the case,you may have turbo probs if it pulls the same as an xe:) | |

Ive got original 1.4 sport pump still on mine, though i reckon it could do with upgrading to handle all the power im now asking for. has been fine for 2yrs though. | |
