Spend all your time making the 60's as consistent as possible first. The WHOLE run is set up of from your 60's. Then go on to the 330 times and see if you are hitting your 1-2 shifts accurately. If you are varying in 330, then find out why. Usually its incosistent shifting , REGARDLESS of whther or not you THINK you are hitting your shifts. A tattle tale tach has helped almost everyone that ever used it. Then watch the 330-660, your ET is all made up in the first eight mile. period. 1/8 th mile is EVERYTHING to do with your ET.
As already mentioned, is the car temp the same, tranny temp the same? Weight ( fuel?) the same.Do you stage the same, with the same procedure? The difference bewtween a full tank and half tank of gas WILL affect your ETs. Work on this stuff first. Dont worry about youe best pass, and your worst pass. Look for consistencies.
