You got your own personnel map or on the generic map? I believe lee has this and has spent a small fortune to no avail. I believe its down to the copied map and if it was mapped to that engine that the engine would run spot on.________________________________________ See the sheer power and might of the lesser known burrowing owl. |

It does sound like a dodgy coil pack I must admit.  ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone  |

The lack of power after 5k is what mine did when the cat was kanckard. I would look at your exhaust in case something has gone wrong with that. ________________________________________ Ex SC-6Now in a Megane R26 |

Fuel pump was the problem , changed the regulator as well as I had damaged the O rings , don't bother trying to find replacements , just get a Bosch 3bar one from a golf , the seals are better (green ) , mine cost me £2.00 complete ! ________________________________________ now new booted , boosted and flying again! |
