I could be wrong, but your injectors shouldn't limit your RPMs. Could possibly be you need to go a few more clicks on the springs?

my rpms can climb good with the 4k kit. it jut doesnt really seem to be fueling that hard.
i might give them a few more clicks. im just scared to take the big plug out. took me 2 hours to get it started when i stalled the 4k kit

if you have stage two injectors, they are not 90hp. 90hp are stage three injectors
