prom tuning help

Hi List

A friend of mine has a 1990 firebird that was originaly a 305 tbi.
Now it has a 350 with a ZZ3 cam. He is trying to sell the car 
but it idles like crap. The ecu is a 7746, I checked on Ludis Langens
home page and found that this ecu is found in a 1987 S10 with a TBI
4.3L V6. Did GM also use this ECU in the cars, he's the original owner
so the ECU is original.The chip is a AXKW if any one has this bin 
could you please send it to me. And if any one has some experiance 
with tuneing this bin please let me know. 

Thanks
