Injectors in----Idle down ???

OK, Heres my unexpected problem:
I installed a set of Bully Dog 50 hp injectors in the 93. I bled the lines and it started right up but the idle seems lower and it has a definite roughness that is noticeable until I rev it to probably 1500 rpm(don't have a tach). This is in neutral/no ac. In drive with ac on its really rough. I took it out for a 10--15 mile run to make sure the air was out but it didn't help any.
The stock injectors I pulled out gave a VERY smooth idle even in gear with ac on.
It seems(from the posts) like most guys see the opposite---an increase in idle when they upgrade injectors.
What should I be looking for---bad injector? ---could there still be air trapped in a line? I sprayed it of with brake cleaner and there are no leaks.
Any ideas appreciated.
