Well I guess I will order a stock pulley then. I was looking forward to a little more power, but I will take all of your advice. I will do the 180 thermostat, drop in air filter, Intense pcm and autolite 104 plugs for now. I need to buy a winter car so I don't have the money to buy headers and an exhaust system unfortunately. Should I take out the U-bend anyway, or leave it alone? I appreciate all the help guys.
