Code three has the advantage of more RPM on the blower that is good, without buzzing the accessories or idlers so much. Currently even with the LSD I can not get on it hard / fast or I blow off the tires in first and second to a bit with 275 Hoosiers. My times are traction limited but I plan to re distribute some weight to see if I can improve that enough to warrent the changes required to do that.

See Word Document of chart of second gear at the top rev level for more. Please remenber that this is with the 178 pulley and code 3 and Boost pressure is measured at the Manifold, NOT wye pipe.
That must be the wrong chart because your only at 1500 rpm. Also with a little burnout at the track you will have no problem hooking up those hoosiers.
