I've got a Procom installed on an America w/904bb,Bub pipes, AI removed and a lightened flywheel by 2 lbs. Not sure which setting it is on but I had a dyno run with the stock map and map #10. Being somewhat heavyly modified I would've thought the #10 map would have produced the most HP. Not so, stock map produce 75.9 hp. Map #10 was a couple less.
