I'm running a TVS2300 with a 3.1" pulley doing 10 psi of boost on the 6 rib belt system and have no belt slip issues. But I changed a couple things to help it out: Using a Gates HD Green belt, HD tensioner and a Griptec pulley. On the stock 3.4" pulley, you'll probably be fine on the 6 rib, just step up to the HD tensioner and a green HD belt.
I also ditched the stock trans lines and went AN. So much easier to route and I always hated the hard lines that came up in front of the radiator.
