Default Idle Drops

Ok, been having some voltage problems ever since I put the underdrive and overdrive pulleys on. So I finally put an under drive pulley on the alt, and now when it is in park the idle is at 700rpm then when I put it in gear it almost stalls out, idle drops to 400rpm then rises back up. A mild cam is the only internal mods with headers, LS6 intake and some other small stuff. 99 Z28

yes, but just mailed the computer off to have it tuned, would changing the pulleys have an impact on the tuning?
