    My mate said we will look at the fuel reg and sus it out, maybe its not working, or what not..
    I upgraded because the previous owner had a VN Pump, back to back with what seemed to be a stock pump, both external. This caused major surge issues when the car was, lets say, sideways?
    I went for the 910 because future plans are a turbo, and previous owner claimed it was perfect with a 4agte, either way, 130lph should be controlled with the fuel reg easily to run fine, like i said, it ran fine for 1-2 weeks, nothing changed on the car, just started a surge on a straight road below 2.5-3k revs ..

    besieds, i dont think its a *surge* because fuel is flat and no matter how much fuel i have it still does it. its got something to do with flow, pressure or like possiblly even spark?

    I'm getting to the same conclusion, im gunna check fuel filter this week end, sparks are brand new so i ruled them out, and yeah pressure seems to be what my mates are blaming.
