How much CFM is that Derale fan? Do you plan on running AC? If so, does that fan kit include a trinary switch? If not, it might be something to think about adding. It basically works in parallel with your PCM output to allow the fan to turn on if the high side pressure of the liquid line exceeds roughly 250 psi. That is if you don't plan on using the pcm controls for the stock AC system.
