i know the basic difference between the apexi safc 1 and 2 being the 1 allows an adjustment of 500 rpm increments where as the 2 allows 200 rpm increments . the 2 obviously will allow a more precise setting up of the fueling .
But will the 1 be fine with me wanting to lean the fueling out with the mods i have?
by the way about £100 in price is swaying me with the apexi safc 1
