You are looking way to hard into this, the original statement the op said was it would sit high 12's at some point which is normal. I am not normal, and that isnt acceptable to me, I prefer high 13's mid 14's at all times. I didnt do it for a bandaid fix, to fix a failing alt (its not old), I did it for my visual pleasure, mid 14's check, windows go up faster check, happy camper.
