Re: IML: 'overdrive' details

["Damian Justice" <djust16@xxxxxxxxxxx>]

yessir, you have to cut, or replace the driveshaft.  They have 
under/overdrive if you are intrested in a quick takeoff followed by high 
speed/low rpm.  I am only intrested in low r's on the highway.  I guess 
nobody has tried it yet.
