if I was to end up having to do this ( id probably start w/ the switch then get the shift nob from PFYC.. but actually having a switch would seem pretty cool, ge one of those little ones from RS w/ the red cover) but yea anywho back to the question.. would i HAVE to get an aftermarket PCM or would i be able to do the recalibration w/ the hand held.. and if so is it setup to automatically set the shift points to such as the earlier years? or would all that have to be tuned? cause i saw its ll the same just minus the shift button so i wonder how much calibration and setup would be needed. does it do exactly what the 99's and so on Performance shift does?! ( i know i asked like 2 questions twice lol)
just curious to know what to expect
