    Lower timing

    Hey guys i average 1 deg lower timing than what is commanded by my Wot table nearly all the time. I have checked all the multipliers and cant seem to figure out why. Could i get some ideas on things that I may have overlooked. Car is a turbocharged 2006 300c. 397 forged stroker. I have checked iat ,ect and there relevant deadbands. Transient spark. MBT table..

    Anyone? Don't want to get into the habit of setting my timing 1-2 degree higher to achieve the timing I want but then have it come in at some random moment..

    Barometric pressure modifier?

    Zero'd out in the sections affected by positive pressure. I know this is a silly common question but I have been all over the tune many times and have talked it through with a tuner and still don't know. Coud it be some sort or rounding off effect?
