Spuddering under boost?

I thought I had a boost leak for a while now because my car was spuddering under boost(yeah I know I need to get a leak tester). I bought the car with some minor mods on it, but, as of now I am currently still in *maintenence mode.* I decided to buy a set of NGK BPR7ES and gapped them at precisely .028. I reset the ecu, let it configure the idle, and now she runs like a champ. I can run full throttle now with no spuddering. Just sharing my experience with anyone who has a similar problem. CHECK YOUR PLUGS FIRST!
