I put a Banks on my truck for the same reason. I didnt see a drastic drop in EGTs during towing but I did notice it took more to get it to those higher levels when underload. The intercooling piping seemed to help about as much as the intercooler did. The Banks unit is nice I will agree that has to be one of their better pieces of hardware, end result is its your truck and it wont hurt it if you want an intercoolers. Thats just my .02 cents, but I also only see my truck 6 weeks out of the year if I am lucky :roflmao:
