Performance wise that sounds a decent result.  What car is it? What fuel pressure does it run? Do you have a bottle heater? Do you know what the bottle pressure was? |

Had the bottle heater been on for a good length of time before you carried out the dyno run? Can you post some pics of how you have it fitted please? |

Can you post some pics of how you have it fitted please? the heater was on about 30 min ish, on and off as it got to temperature it was then off for about 20 /25 while it got put on the rollers and we done the first run but the preasure did stay at 900psi will get some pics up tomorrow but the heater sits under the bottle if that helps for now cheers john |

OK that rules out falling bottle pressure as the cause for the lean to rich swing. Awaiting your pics of the front end to assist further. |

The fit looks about right, so that's not the problem. It's an OLD system so have you replaced the nitrous filter since buying it? Have you got a progressive? |

That leaves me with one last option; The jet sizes are a little too rich and the initial leanness is due to the nitrous reaching the engine first. The lean to rich process is normal to some extent and the best solution to the issue, is to fit a Max Extreme and utilise the nitrous only delay feature and fit a smaller fuel jet. A cheaper but less satisfactory solution is to increase the length of the nitrous pipe between the Pulsoid and the D-Block inlet. |
