Cooling fan will not cycle off!

[Jjohnson2]

To all,
I can not get my cooling fan to cycle off after it starts. I changed out the fan relays and that did not work. I do not have an overheating problem. I have american racing S.S. headers which I don't think would cause this problem. I had some one go into my computer to adjust my speedo for 373 gears could he have screwed some thing up or is this a common problem?
Thank you,
Jim Johnson

Sounds like your tuner may have messed with the coolant fan temp settings. Perhaps be meant to lower the temp to 180 degrees, and by mistake made it 80 degrees or something along those lines. I'd go back to him and see if he can figure out what happened.
