He`s a very good mapper and he`s a very good mechanic. But he prefer to map aftermarked ecu`s . He also told me there was a strange smell when he opened the ecu. Smelled burned . |

The afr was very good all over the place. But the warm startup is so strange. But l can tell you one thing. Tomorrow lm gonna buy a DTAs40 because l m sick and tired of this. |

DTA is a good way forwards, I use an S60 Pro and can't fault it.  ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |
