When wide open throttle, pedal to the metal and on boost, the warmup regulator will enrichen the mixture quite a bit. So, if you let off partially on the throttle the boost pressure will be diverted and the engine will lean out momentarily...which may cause a brief acceleration as you discribe. I don't notice that in my car, but then I've got it pretty well tuned in with an adjustable WUR. Your car might be too rich either on or before boost, I suppose. Or perhaps just the opposite is happening with too lean on boost and getting richer when you let off.

That's my guess, anyway. Anybody else got any input?
