Wanted to get some opinions, will an ARH system give me some good results. Just curious cause i have read of trucks not having enough back pressure and crapping out or resulting in no gains. Sometimes even losing HP and tq. I'm not no 6.2, im goin to be a 4.8 with a nice header set up. Is it worth it? Current mods, GMPP CAI, and Cat back Magnaflow, two in two out. Getting black bear tune in Feb. Trying to make a decision soon, so i can have them on for the meet. Please give me your opinions. Im new to all of HP stuff, so its hard for me to make a decision.

  And there aren't any "bellows". There are solid plastic doors the actuators move, which largely seal just by themselves, and then have a strip of foam around the edge to better seal the door. The foam does deteriorate over time, but this is unlikely to be a significant cause of the problem.

  are the heater controls set for hot or cold air? If it's set for hot, and say, to get air from outside the cab (vs recirculated air), even w the fan off, air will get pushed through the hvac system, over the heater core and into the cab. Switching it to cold will reduce the temp to whatever it is outside. Switching to recirculate mode (which may mean switching to vents or whatever, read your owners manual), will reduce the amount of airflow through the hvac system.
