Kohl,

You car runs excellent on 3.55's

Having thought a bit about it IMO I would not go through the agony and expense of changing gears... my 2 cents

I did it on my convertible and I am pleased with my 4.10s but is a much heavier car and I am a heavier guy too.

(BTW bro I think there is something wrong with my tune. Put on a strategy tune to prepare for an emmision friendly tune (O2 sensors on) and the car feels pulling harder... I will have a talk with brenspeed...)
