I see that that fan temp. settings can be changed the stock temps. seems a little high those with a tuner what do you have your fans set to come on at?
With a 170* t-stat I set mine as low as it would go... 182/186.
The fan settings can go lower, can be anything you want really. If you're setting them from the handheld the range you have in there is pre determined by your tuner. So each person's hand held will have a different range of options depending on what their tuner put in there.
