trust me its quite obviously slower than before!! theres just nothing there....!
Alex....yea sorry i meant its basically bang on 0% cos the gauge is +/- .5% so that kind of confirms if its -.5 out its still 0 (if that makes sense

)
....maybe it is actually okay, not sure what the co should be but i would guess 0.5-1.0 or at least more than it is? otherwise any other ideas for its apparanty lack of life.
