Eric, haven't reset the comp yet. Will try that later today and see if it helps. Also, I talked to a buddy of mine who's an ace mechanic and he suggested something since I told him I was also getting a wisp of smoke out the exhaust now when I get on it. He said there's 2 possible things to cause that. One being that the air/fuel mixture is off now with the increased airflow and it could be too fat or lean. The other being that there's a chance the element was oiled too heavy and what can happen then is the intake sucks the oil into the TB and gums up the mass airflow sensor. According to him, if this is the case, that will eff all kinds of stuff up and I need to blow some of the oil off the element with compressed air from the inside out, then get a can of mass airflow sensor cleaner from auto parts and spray it in the TB to get the gunk cleaned out from any filter oil residue. Ugh.
If it is the fuel mixture, I would think resetting the ECU would solve that. If not, I'll go the cleaning the mass airflow route. Just figured I'd give you guys a heads up for future reference.
I dunno though. When I had my AirRaid on the other truck there were NO issues. Now I get a K&N and it's been a huge p.i.t.a. :/

Reset the comp today and put about 20 miles on it afterward. No change in the sound/vibration/shudder during hard acceleration, but I didn't notice any more wisps of smoke from the exhaust, so either the air/fuel mixture has been adjusted to normal levels or it blew all the filter oil out of the intake system. Whichever was causing the smoke.
Thanks

idk if the 63 series is considered the cold air but i noticed an increase in the noise from the front end after the install. when i stand on it. but under normal conditions wouldnt know its there. i like the sound though but ima look at cleaning out the T/B and ar flow now that you mention it see if that changes any thing

From what I can tell on my truck I have an IAT/MAP sensor as well. You can't just use an IAT, there has to be some other metering device such as a MAF or MAP sensor in place. The IAT only corrects for density change with temperature measured by the air metering device. A MAF sensor estimates airflow based on the amount of electricity required to keep a thin wire at a given temp (increases with more airflow) while a MAP sensor calculates the amount of air inside the intake manifold based on the relative pressure when compared to ambient.
A MAF sensor is always mounted before the throttle body in the intake tube. It is usually a little box on the tube mounted just behind the air filter. If your truck (ours) does not have a little sensor box on the intake tube it uses a MAP sensor.
