In order to run smaller pulleys, you need to do other upgrades to accommodate the boost. you will also have to regularly scan for Knock Retard.
a 3.5 pulley should definitely run with zero KR with the thermostat and CAI, and possibly a 3.4 would net the same results.
Anything smaller than a 3.4' WILL require more intensive modifications in order for the engine to be able to handle the extra boost and not start to knock, therefore reducing timing, and possibly causing permanent damage to the valves and or pistons
