Default More fuel??!

Alright so I just installed my new Industrial injection stage 2 80horse injectors. And here's my question... I think my idle may be lower? I thought it was 1k but now it's like 800. And when I coast through town and kinda step on the throttle it seems like it wants to die? And when I mash it doing wot it kinda sputters at first then runs fine.. Is that a sign of I messed something up? Or need more fuel. Or afc tuning?

Anyone?
