Glad I found this thread as I've been wondering till now.. the fact that my intake temp as rocketed since fitting the 6637 so my concern was although I'm getting more air its a lot warmer hence no real increase in power?
I already had Bully dog stainless exhaust fitted so maybe why I didn't feel a difference with the 6637, just cool noise

I mainly run a tow tune (60) and see around 18psi when pushing but only 3-4 psi eco/soft driving and at $12.00+ a gallon its my usual drive style regrettably lol!!
I do know my driver side red boot is damp oil covered, since pulling my 5th wheel, I have cleaned it to check if it returns but then my trans pump seal started leaking so off road now getting new seal, Tugger and tru-cool fitted.
Other boots have a dusting but dry and I guess normal build up over the years?
