Default Engine surges at idle after WOT runs...otherwise ok

My engine surges at idle, but only after WOT runs. If I nurse it around for awhile, it's back to normal.

My feeling is that I need to either drill the TB more or add idle air slightly...any suggestions that will mke this quicker to dial in?



232/236 cam, Patriot heads, headers, stock maf and LS intake, shaner tb with .100 hole.

Yep, I'd try bumping the Idle air (RAF) a little. From what gojo and NoGo have posted this would be my first move.

Before any of that I would take a look at what
your engine coolant temp is. May just be way
overheated, stock program has fans not even
started until 224F stock and heads are hotter
than that; fan settings might fix it all?
