im building a 1800 pound car and am gonna run low boost .. like 7-8 psi .. im not building the car to whoop ass ... just to pick up chics . lol .. nah im goin to eventually get up in the 20-25 pound range .. billy T has helped me out with a basemap to get me started .. but its gonna take some tuning to crank the boost up that high safely . i also have the juice on there so i dont think 400whp should be atainable
