Hello,
I have a 2004 Tahoe LT that I am going to be upgrading to the E-fans
I am going to have Blackbear set me up with a traditional tune which I will than get my pins turned on in the pcm for the fan control. I will be getting the Blackbear E-fan harness at the same time and was wondering on the alt pulley if you think that is something that I should get? The truck has a 140 amp alternator right now. I was thinking of the Dorman fan 620-654

If you have any other ideas that you guys can think of would you please pass them on.
Thanks Craig

That alt should hold it just fine. I have the factory 145amp alt with the e-fan upgrade & I notices zero problems. None...don't even feel them kick on...
