Alky Pro is being used by a lot of the top racers over here in Australia now very user friendly and Greg Gower will give you the after sales service if you need it .
There is a free two week trial version available on the Alky Pro site try that and you will buy it .
I run the F.A.S.T air system in my car have never had it Fog up and I turn it on when I get in the car and its a lot more comfortable as it gets hot down here in Australia
