Get ahold of CPR ( central performance rigging ) i think thats what it stands for. They are off D rd in Osage Beach, or try Advance Marine over off W rd they do maintence on David Scotts Skater's. Gene at lightning engines over on highway 5 outside Laurie should be able to help also. Glencove sells and installs Prochargers i would think that they could install also.
hope this helps
Did you buy your 40 from AJ at Hawkeye Marine in Iowa
