Idle Surge.

Idle surge is caused by the engine not being tuned properly, or the improper parts being used. I've got multiple Blower Engines, and the little motor 468" runs 9.2:1 compression, and 7.4 lbs of boost. It idles at 880 RPM and has absolutely no surge what so ever. You have to first pick the proper parts, and then tune them properly.
