I just put swamps stage 2 split shot injectors now it knocks at an idle. the reason I put new injectors in is because it was burning oil #8 o-ring was bad. I made sure they were completely seated and torqued to 120 inch pounds. I made sure the seats were clean and vacuumed out the cylinders. I still have to send my chip in to get re-flashed could that cause the knock? the truck has 234,410 miles on it thanks in advance

Definitely need to be running the right tunes. Check your fuel pressure as well.

swamps says these injectors will work with the factory ford programming. fuel pressure is around 60 psi

That doesn't mean you have 60 psi.
