There will be a lot of opinions on this one... and mine is to shut off O/D, put it in "D", and floor it (once you have traction).

My opinion is that for 03's you will benefit from manually shifting your tranny. 04's and 05's with superchips don't need to manually shift because the shift points are already raised to 6100rpm's. I have never tested the differencs between tow/haul mode being off or on so I can't comment on that, I don't see how it could make to much of a differnece though.

I take that back, on 03's the overdrive on/off button will keep your transmission from shifting into overdrive regardless of speed at WOT. So if you have 4.56's and short tires and your worried about shifting into 4th you should turn od off. That way you could take 3rd all the way up to the rev limit of the engine.

This past weekend I took mine out for the first time and ran 15:450 with it D and floored; 15:444 in Tow/Haul D.
Don't know if it makes that big of a difference but my 1/8th and 1000' times were slightly faster on the 15.45 run than on the 15.44.
