Helix, Detroit Tuned and WMW has them for sale. I know I am not getting rid of mine anytime soon.:devil:
Suffice it to say that if ya think your going to pick one up used on the cheap......it ain't going to happen.
Given what one cost, do they really help that much? Wouldn't water/meth injection be more bang for the buck?
They recently doubled in price! Last year... $400... Now Kinda makes the price gap between a new GPIC, and the copper cored DOS I/C look not so bad. The DOS is the only one I know of to ever beat the GP in track conditions.
