Are you controlling timing with the Sniper? If not you should be. If you are then throw a lot of idle timing at the engine. Start at 25 degrees and then test 28 and 30 to see how it responds. Watch the MAP and IAC values as you change the timing since those two numbers will show you if the engine is getting happier.
