AIS Filter

Started replacing performance parts on my 2003 F250 7.3L PSD (currently has a Banks Stinger Plus kit on it). Put an AIS intake on it, and immediately pegged the filterminder on the first short WOT run. Read on the forum about replacing it with my original filterminder. I was still able to get the filter minder to pull about 50%. My original airbox didn't ever register on the filter minder with a clean filter. So why am I now pulling on the filter minder with (supposedly) a better flowing intake? I believe I'm pulling more air as the smoking is all but gone, and first two tanks of fuel show a slight increase in mileage. Trucks "feels" like its running easier. Is it possible that because the engine is running stronger/easier, it's increased the demand for more air?

I'm interested to hear feedback on this too. I've been running the Banks Ram Air, but just ordered an AIS last night, mainly for peace of mind. I'll be running the fender sleeve with mine. All I read said that the AIS was good up to about 400whp which I am no where near. But I do run a DP Tuner 80HP tow and 100HP street tune. Don't want this to be an issue by choking my intake air down.

Well, I got my AIS filter kit in and installed. I'm extremely happy with it so far. It does make the motor and turbo more quiet inside the cab. I am running mine with fender hole cut in. After making a few hard pulls on the DPTuner 100hp street tune at about 28-29lbs of boost, there was no sign of restriction on the filter minder. I also towed my 10k lbs trailer using the DPTuner 80hp tow tune pushing up around 26lbs of boost with no sign of restriction on the filter minder. Call me impressed!!
All of this is over about 1000 miles of driving this week, half of it while towing.

Sounds like I need to order the fender sleeve. Interesting there were no other explanations. Thanks for the info...
