Yes, it's as simple as buying a smaller(higher psi) pulley, having it installed and then dyno'd. That ruins the warranty though if u bought one. U would only need to upgrade to an intercooler if u run high boost. Most people consider more than 9psi highboost. Chrisc has the non-intercooled vortech and a 9psi aftermarket pulley. With that combo and an aftermarket muffler he dyno'd 270rwhp or about 320-330hp crank. Some think that's the highest boost u should run on a non-intercooled vortech. U right now with the 5psi pulley(i think it's 5psi or 6) would dyno around 230rwhp. So just by upgrading ur pulley u can add 30-45rwhp(9-10psi pulley). I was gonna runa 10psi non-intercooled vortech next yr until I thought about resale value. U will not have to worry about needing anintercooler at that low of boost as long as u drive pretty muchthe same as u did before u got the charger. Good Luck on whatever u choose!
