E-fans and alternator pulley

[jetblast]

I am looking to install efans on my 2002 tahoe and was just wondering how programming the PCM to control the e-fans is done. Do i have to sent BB my PCM of something else. Also if I install the alternator pulley do I need to get a differnat size serpentine belt. any help would be great thanks.

You will need your PCM tuned to control the fans. We have a few different tuning options, which can be found at www.blackbearperformance.com/services.asp

You don't need a new belt for the pulley.
