Like putting on big wheels on a car, your speedometer might read the mph higher or lower than the actual value .. but since it starts at 0... does that mean its accurate? |

I don't see them losing as much power if any than the crappy stock diverter valves. Some people are just biased towards bovs because they don't think they belong on a BMW. Bov have been on high hp cars for years with no issues, now thats its on a bmw its prone to leakage and not worthy.

Do not assume the dyno boost measurements were incorrect; verify they were incorrect. You should assume they were correct and then determine otherwise. Just FYI... |

But thanks for the time you took to write your response. And FWIW, there will aways be some disparity between TMAP readings (from PROcede software) and MAP readings (from the manifold) since there is a activethrottle body in between them. Not to mention the fact that they are inevitably calibrated differently. Cheers, Shiv |

Looking at the curves (not a peak) shown on page 1, they appear to coorespond within reason.

I wasn't there for the first couple cars but one of the guys said that he was seeing 15-16 psi on the boost gauge when it was saying 19 psi on the dyno.
As far as assuming something is true until it is proven otherwise, then maybe you could assume the boost gage was correct and the dyno wasn't.

Again, speculation is not valid, someone should have verified which is easily done. |

16.7 psi for 91 octane? Isn't that high for the procede or is that normal?
