do yall think because of my modded stage 3 pump i am not gettin enough fuel with my AD100 to the cp3 pump is why i am not seeing hardly no power diff with my flux 2 sticks..need some pointers guys..lot of $$$ in sticks for no extra power

BossHogg

wow, first I've read about that. I have mine still sitting at Don's to be shipped/installed. Anyway, I would say that its possible that your AD100 might not be flowing enough, but if thats the case then Im in for a new pump as well. Im running the stock CP3 and a GDP392, so I would think that the AD100 and GDP 392 are similar in output....but maybe not.

Maybe some of the more knowledgeable members will chime in soon......I'll be following this one.

How is the rail pressure acting. Is it holding up ok?

Did you have stock injectors before?

WUnderwood

what kind of fuel pressure do you have going into the cp3?

kdbvulcan

i just found out that i am obviously not getting enough fuel to my cp3..plus what makes it worse my cp3 pump is modded to a stage 3..so i am gonna have to upgrade to the AD150

madhat

How did you find that out?

When we talked before, didn't you say that you had a FP gauge, and that you had good FP?

kdbvulcan

yes I had stock injectors bfore...rail pressure is at 26,500 then falls into the low 20's.....but I have Johns modded stage 3 pump do you think my AD100 is gettin enough fuel to the CP3...i know the AD100 orange light comes and starts blinking when you hammer down on it...i havent checked my fuel pressure yet...surely to goodness i should tell a diff with youre flux 2 injectors in their not??

BossHogg

Well from what I've read on here you need to monitor your FP and RP to be able to find out where the lack of fuel is coming from. Makes sense that if the FP is good, that the rail pressure must be lacking and therefore your pump cant hang.

kdbvulcan

no i never put a fuel pressure gaugre on it...been aiming to just hadnt got it done yet

dieselram_04

well if the light is blinking he is below 5 psi pressure.

Don M

I would think gettting the fuel pressure issue cleared is the first step.

Going from a stock injector to a 2.5 is a big step. Certainly it should be easily noticed.

kdbvulcan

are you the guy that did them??..i went through John at floor-it-diesel...i am gonna upgrade to the AD150 and put a fuel pressure gauge on the truck and then see wat it does...if they still aint no extra power i will have to pull em back out and send back to you and let you look at them....thanks guys

BossHogg

Yes Don is the man behind the F1 products. If they are not right, which they should be, Im sure he'll help you fix them. I'd look at your fueling problem first.

BTW, what type of light are you refering to that comes on when the FP is below 5psi? Is this something that is on the 03-04 555's too?

kruegerlouie

not to steel the thread but don,how much should a set of 2.5 smoke,mine were the ones you changed from ddp 90s last fall?? I know theyre much better but used to the smoke from the90s,and these should be arond 125hp range. thanks Luke

madhat

My 2.5's barely smoke unless I set the truck to kill... only a slight haze when the motor is cold...
