Is it possible to buy SCT software? I had my '95 Cobra tuned at the shop a year ago but recently installed a slightly larger roller cam and larger throttle body. It runs okay except for a slight hunting idle, but I wouldn't mind being able to make some fine tuning adjustments myself without taking it to the shop, i.e. adjust idle mixture, etc. Is it possible to buy the software or can you only get it if you are an authorized tuner?
