Surely its down to the fact that the air flow meter has measured how much air has gone into the engine and therfor the ecu calculates how long the injector stays open or in other words how much fuel to put in and whats happening now that you have fitted a dump valve some of that measured air is escaping and leaving behind a more fuel to air mix.
Im having a **** time aswell since fitting mine, although I would be happy if I was getting your results, all I get is hunting and stalling at junctions. I will have to return to the std dump valve and hope ive not ruined the MAF in the process.
