Hmmm, that is nice you had yours tuned. Mine is not. Seems like my first fan kicks in at 185-195 on low and then it kick on high at 205. Around 210 both kicks in at high, which is extremely nerve wrecking to me. Around traffic I see 200-205, with or without tow. Who did your tune and how much did you pay?

I have a handheld tuner but since my PCM has some tune files that were not completely deleted my handheld is not compatible.
