    I am curious, too, as I have some popping.

    I know the information is here for a zealous searcher, but I would like a nice summary of the recommended airbox mods, jet changes, and cat removal procedures (yes, lazy :). That airbox mod thread must have 400 replies!

    My cams have been modified I have no cats and an open air box so I went with 70 idle jets and 165 mains. I would try moving up one size from stock. Which pending on the car is usually a 60 idle jet and a 145 main jet but check your own because it may have been rejetted already by a PO. At this price though I would go ahead and buy sets 1, 2, and 3 sizes bigger. For an extra 25 bucks you can save yourself the delivery time in case they need to be a little bigger. Make sure your mixture is set right and your carbs are sync'd because that could also cause a little popping. I'd also recommend a hotter plug if you go with bigger jets.
