I have 2G 95 TSI AWD Automatic with several mods. After I drive the car around for 10 minutes and it gets hot (200-205 degrees), the idle will begin to climb to 1500, 2000 and as high as 2500 RPM. Once the car cools down it is fine. I hot wired the fans into the boost switch so that whenever I am at high boost the fans are always on, does hwlp a little. Last year I did replace the ISC. This seems to have happened since we made the turbo swap and SAFCII install. Any help appreciated.
 
It appears that if I leave the "hotwired" fans on continuous the high idle problem never exists.
