Does anyone know if the pusher fan mod works as well as the dual fan conversion? The intention is to get better AC temps while parked or going slow. Going to the Dorman dual fan set up on my previous Suburban really helped out but they were costly once it was all said and done. $200 new Dorman fans $115 Nelson Performance harness $300 Local tune + program PCM for the fan (would’ve been 150 for just the programming) $615! Total VS A single decent pusher fan plus wiring. ~$200 Thanks in advance!
