vp44 fueling issues

[underminded01]

well where do i start? i have just put a set of 6x18 injectors in my truck and after finally figuring out i had to run my stock lines for it to start and run right. now i have a new issue last night i hooked at mason dixion dragways pull and when i come off the line the rpms shot straight to 4400 then fell on its face then right back up to 4400 then right back on its face. why is this? cant figure out what to do to keep it at a steady rpm not jumping up and down? This is the video on youtube below.
