Interesting point about the tune. Has anyone ran lean with no tune and big pulley?
Brian doesn't run lean because of his stock intake plenums. They bottle neck and give a higher reading at the MAP sensors then what is actually seen in the plenums. Moddified Plenums plus 181/185 pulleys take you over the edge. Lets
sue Needswings and 240M3SRT for this it is all their fault.
I'm first on the list, Oh wait I didn't use any of their stuff
, but don't let that stop anyone else
