So with 11mm and 11.5 available at valve max and the stanard lift of 9 .17mm this doesn,t leave us with much to play with.has anyone ever tried a regrind on the standard cams for say an extra 1mm and more duration,if so how much can be removed off the base circle before we run out of lifter and can we get away with the standard ecu with a mildly uprated cam (or have I missed a post somewhere)
