I'm going to install a s/c pulley and i was wondering if i need to upgrade my injector too? will it work with my stock injectors or will i get too lean? need some expert advise...

My 2006 MCS has been running a 15% pulley & stock injectors for about 85,000 miles with no problems what so ever.

You would only need bigger injectors if you were doing headwork or a cam.

No you don't need injectors for just a pulley upgrade. 90% of customers dont ever get injectors, the car doesn't run lean with just a pulley.
