Recently my car has had this annoying stumble. Only happens right when I get step on the gas. I can feel the car hesitate for a split second then it goes off smoothly after. I cleaned the tb and iac. IAC counts are around 17-18 in park, engine warm and a/c off. I have a PTE custom alky chip, a kirban maf sensor(still saving up for ls1 maf and trans plus). Could a dirty injector cause a stumble? How bout a bad maf? Should I raise the IAC counts?

Lower them and see if it fixes it.
The stumble can be caused by the transition from IAC to the throttle blade. If your IAC numbers are real high you'll get a lean spot just off idle.
Personally I like to keep my IAC's very low. As long as your count's never hit 0 you're fine.
don't forget to reset your TPS too.
