Installed the 2.93 pulley today after work. The pulley really has kicked my car in the arsce, but my tune looks to be really rich. When I nail down on it, I get a cloud of black smoke from the rear. The car pulls strong and hits hard, but I definately think it will need to be leaned out some. I also noticed, after installing the pulley, that the blower is alot more audible at part trottle and cruising. Is this normal? Before you could hardly tell I even had a blower but now it is kinda obvious. It is not LOUD, like something is wrong, but you can hear a slight wine at low rpms. I will be srapping it down to the dyno on our dyno day next month to see what kind of power it has and to see where the air fuel is.
