Just bought a 2001 Tahoe. It appears to be in pretty good mechanical shape for 245k miles, but two mods I definitely want to do are BB tune and efans.
Now suppose funds/logistics/impatience prevents me from doing those two mods at the same time, so I go ahead and get the BB tune first. Is there any reason why I can't just have them turn the efans on in the tune, but keep the clutch fan as is? I'm not 100% sure how the clutch fan actually engages, but I assume it will keep running as long as it's attached to a spinning pulley. And as long as that happens, my temps will be fine, and having my pcm turn on fans that don't exist won't create any other problems, correct?
