Deadtimes, help please

[Redsi15]

I have some precision 1000cc injectors. I can't get it to idle smoothly and was told it could be do to dead times. I've searched and searched and can't find deadtimes for them. Really need to get car on the road. I had flow tested and cleaned and they are flowing at 980cc. And if any other info needed let me know. Also my a/f is at 12.5. Any info of what I should do to get a/f 13.8-14.7. Thanks for your help

Have you contacted the manufacturer of the injectors for the correct dead times?
