Can the shift points be adjusted by repositioning the TV cable? It shifts around 3500 - 4000 rpm and is a pretty hard shift. This is great for aggressive driving, but when I am just cruising around town I don't like to draw attention to myself by driving at high rpms and barking the tires on the 1-2 shift. I was told by the previous owner that it does have shift kit, so I realize the shifts will be somewhat harsh, but I would like to improve the driveability of the car. Any suggestions?
