My Warlock feels like it's dropping spark above 3,500rpm and surges pretty hard. I'd like to go ahead and get a backup ECU to have on hand and try while I'm looking for the root cause.

Is a parts store version a reasonable choice, or is there a particular vendor to seek out? Not looking for a $200 RevNAtor unless it's going to rock my world.
