I just started my 91 jsppec with a 87 t2 cpu . I have 720 secondaries and red tip 550 primary . Any how when it started It idle about 1500 1200 rpm and it sound it a little rough like a miss fire I then took it up my drive way when you get on the gas it kinda loses power . I then thought **** maybe I mix up the high imp. j spec injectors with the low imp. injectors . I then took out the 550 and replaced them with another pair I had these where kinda teal green tip . Now my car sounds like a lawnmower . WTF I m gonna kill myself !!!!!!!!!!!1 Just kidding I going to kill mr wakkel for not helping me

 

who is mr wakkel ? Would the 91 jspec motor work with the 87 comp? Aren't the cpu's setup for different compression ratios and all that Jazz?
just a thought, I know nothing of the matter....

 

How are you controlleing those 720's? Without a fuel controller you'll be running rich whenever the secondaries come on. Which will be why "when you get on the gas it kinda loses power." Sounds like it's now running on one rotor, meaning one of the newly installed injectors isn't firing.

 

Just a word of caution: SCREW identifying injectors by color. Use a simple digital meter across the injectors prongs to measure high or low impedence.
