you're pretty close to the zone ( the 3% ) that you want to avoid whenever possible. it will dry out the vc if you're activating the psm for no reason other than some straight-line acceleration. turning it "off" is only asking it not to "notice" it and respond with the same degree of sensitivity as when the abs/psm is "normal".
