6637 installed today

Just installed my 6637 filter. Can't wait to see feel the difference. Not a bad install the biggest problem was getting the orignal air box out of the bottom rubber grommets. What can I expect in way of performance or fuel milage, if any at all?

its really not that big of a difference, your engine feels it, your pants wont, you hear the turbo sing and its fun to listen too, i havent seen much a difference in mileage.

Great to hear. Your improvement will be small, but your turbo should be louder, especially when you get on it. I didn't have noticeable improvement until I installed my 4" exaust and 3" downpipe. Then, holy cow, you can really tell she's breathin easy.

Where did you get the 3" DP? Exhaust is next...when I get the $. It's all stock for now execpt the 6637. Had to take out the Superchip the previous owner intalled in 2002, it was making my truck die and not run right every now and then. No problems since I took it out. I can't noctice a difference with the chip out around town. The test will be towing the travel trailer up grades in a week.
