i just installed a rail pressure gauge and I have a few questions at idle 7500 put in to gear jumps to 10,000 with my triple dog 2.3 pl race program on and quad box on towing I am steady at 18,000 psi at WOT and 109 mph this is with a single stage 2 cp3 and my flux's 3.5 does that sound normal?? I usually on run just the injectors while driving no quad or triple dog

I dont know about the 10k at idle as I dont have an auto but 18k sounds ok but could be higher

I just DIYed my little bothers pump and he said that he can hold 25,000 with a quad zxt and tst on 6x4, 7x3 pulls pressure down tho? His pump is stock btw.

Mine reads around 22000 wot, and around 6500-7500 at idle

You are losing power. Keep it between 22k and 25k for the best power.

Currently with no pressure added, i'm around 17-18k at WOT on Crazy Larry. My injectors are bigger than yours too

This is about what I'm seeing too.

Smarty Beta 4.4 level 5: 9-10k idle in gear, 18k cruise on freeway, 25k WOT

I have flux 3.5s and a Floor-it pump, and I can stay at 21K or a little more at WOT with standard Smarty, and 23-24K with Beta 4.2. May be due to the quad/ Bullydog stack is draining your rail. But you should try to tune to stay at 21K or more, and you should see improved performance.

18000 is getting a little low. With my diablo, juice stack I see 24000 without the juice and 27000 with the juice on any setting other than 5. With the juice on 5 pressures run about 23000 and it makes ton of smoke.These pressures are the same whether I run the diablo on performance or extreme. With your modded CP3 you may not be able to keep up with the stack but you should see more than that with just your injectors.

18000 is a little low. Make sure you plug the gauge in first then the Quad as you might be seeing what the computer is seeing when it fools it. I see over 25K with bete Smarty and when I stack pressure I see almost 30k with a Floor It pump.

Mine is running about 24-25K @ WOT with the Quad STD on the highest position. Idle can be as low as 5-6K with the Quad turned off.

thanks for the info

I would put your downloader on performance and see what it does, your demanding lots of power and your rail can't keep up with it.You could even
turn the pressure up your lift pump and that could also help i had my at 28 psi. when i was running a single modded cp3
