Product reviews for BD Diesel Boost Fooler - Dodge 1998-2000 w/ Round Map Plug

As advertised, this product clamps the MAP sensor voltage to prevent the ECU from "seeing" increased boost levels (from fuel/air upgrades) and defueling the engine/throwing CEL code. Generally, this works best when paired with a boost elbow (to allow wastegate to open at higher pressure), currently not available on BC Diesel's site!
