What are symptoms of low valve spring pressure during a pull. Thinking I may have a problem with them. |

What is your seat pressure. Open or limited rpms? Turbo? |

How much boost are you making and what are your valve sizes? Also seat pressure? |

Boost is 65lbs not sure on seat pressure. Runs almost the same in 2 gears gets towards end an just dies out. It used to pull both gears easy an pull to lower rpm then it has its last several pulls. Never really changed anything was just curious if valve springs have gotten weak. |

Your seat pressure needs to be AT LEAST 2 times the boost pressure. And it doesn't matter what size of turbo or rpms that you are turning. Now there are many that will disagree with me and that's ok. |

Been there. In my situation the waste gate didn't open up to where I had it set. It didn't have to as the valves became the waste gate. |
