cam swap...NEED HELP!

okay guys...to start with i just swapped cams. its got the ai 226/234 with 30# svo injectors, pro mag rockers, blah blah blah and i got the computer tuned by madz28 while i was working on it. well the car will start up and run, but its not running right. when you hook a computer up to it, it says the desired idle is 3188 and the cars runs EXTREMELY rich. so rich, i was crying after taking it around the block. i don't think its timing because it doesn't pop at all. do you think its in the tune?

Does it say the desired idle is that high all the time or just when you turn the ignition on before the engine is started (which would be fairly normal)? Once the engine is started the desired idle should change to something more normal.
