You mean your high speed fans are on all the time no matter what temp? Low/high speeds are set to come on/go off at set temps. Don't know why a tuner would just program them on high all the time - give them a call and ask. Nothing else going on like SES, overheating, etc.?

I'd definately give them a call like NBM said. You'll burn out your fans a lot faster if high speed is always on. I have a stock 195 stat and I set mine to come on at low/high on/off 208/197 and 217/207....the fans cycle on and off great at those temps.
