HFS-5 messing up with 1000cc inj!?

HFS-5 messing up with 1000cc inj!?
just got my fp red put on along with 1000cc injectors and using aquamist hfs-5 v10 with it and the 1.0 nozzle.. 100% alky
well now my pump randomly kicks on and it flickers on the gauge almost like it was a bad ground triggering the fail safe (yellow led) on the flow meter gauge
do i have to adjust the trig sensor any? its at 24% right now or anything different to be able to function well with the 1000cc injectors
the kit was working fine before the turbo upgrade last week and started doing this as soon as we started it up and messing with some TUNE-age..
..help?
UPDATE:
thanks richard and everyone else on here, i went with the double pulse method and added 2 diodes to both injector #1 and #3 and played around with the trip adjustment.. now its smooth again.. sucks that i now need a new clutch.. meth made it slip as soon as it was turned on to tune
act < exedy TWIN!

If a system is flicking and inject randomly, it most likely to be a wiring problem. Check the impedance of the 1000cc injector. The EVO have resistor packs, if there is a mis-match of impedance, it will not work well.

how do i know if there is a mismatch of impedance?
im using percision 1000cc btw

If everything was working great with your HFS-5 beforehand chances are that your FiA2 is sensing the the wrong IDC% from your huge injectors. I am running 1000cc RC injectors at a very low 49% IDC by redline with my HFS-5 for several years now. I am running twin 1.0mm nozzles I am double pulsing my injector signals. Here's a diagram of how I did it with the help from Richard several years ago.
The only change that I did to the above hook up is that I tapped into the #1 and #4 injectors. I used a pair of 1N4007 diode with my set up. Hope this helps.
Edit: I just re-read your op. Did you switch over to 1000cc injectors along with the FP Red when these problems began? The above diagram will only work if your IDC% is to low to trigger your Aquamist due to the addition of much larger injectors. Otherwise scheides has a very good solution. Sorry for any confusion.

thanks man and yes these problems began as soon as i switched over to the red/1000cc. yea im going to play with the trip adjustment and turn it up some to see if it helps
and im running the DDS v10 so i dont have Fia2 and the board is a little different

Your diagram is just fine and no diode is needed with that set up. I tapped into the #1 and #4 injectors to get a double pulse signal to my FiA2 which is a part of my DDS3V9 set up. That doubles the injection rate to the nozzles to compensate for the low IDC that the Aquamist is seeing. In your DDS3V10 diagram I don't see that a FiA2 is used like on my V9. Richard will have to chime in on how to advise you on that. The technology keeps changing and my DDS3 V9 is looking old school now.

Sorry for all the questions, just trying to get a better idea of what happening and when.

Where is your pump and relay located? What do you mean by "randomly kicks on" does it happen at idle or at low load cruise? Or do you mean it should have turned on and it goes on and off. Is the yellow led the only flicker light or are you also getting bars like it is flowing meth.

"randomly kicks" at idle mainly
it activates fine when its suppose to at regualr load
yellow led flickers on and u hear the pump turn on in the trunk for like a couple seconds off and on.. but basically random! hard to tell when it would do it
no meth is flowing on the flow meter when the random problem is occuring tho from what the flow meter gauge is showing
