Matts Colorado weighs about 100lbs more than my fully optioned 98 Trans Am 3725lbs with me in it (given Matt and I weigh the same, he is much further along on his Keto Diet than I am).
Congrats Demark!
Also congrats on the new edition on the way!

Nice work and thanks for the race render vid. Fun to watch.
I can almost guarantee that the FPR doesn't 1:1 with boost due to the regulator. Anytime you have a multiple pump set up that is "on all the time" you typically get out of the acceptable range of the regulator to get base pressure down to where you want it. One solution is the "donkey dick" Aeromotive regulator or if you don't want to spend any money and you have the capacity, set the base pressure higher to get the regulator back in to a happy place.

yeah i would have to verify with a mechanical gauge because i set it at 40psi~ area when i put it all together,
oh well, lol, i also have a triple pump relay controller i havent wired up, i am going to de-mod the truck anyway to pursue more ecnomical setups now that i have hit my all in goals i am bored with it as is, would like to work on another project i have for fun and then change the whole engine, cam, electronics fuel, etc setup in the truck

Not trying to be a smart *** so dont take this the wrong way. He can also leave the set up alone its working just fine for him and hes only at 51% dc on the injectors. I see no need to mess with it. If he was running out of injector i could see making the some changes.
In my case when I went through this problem as it was causing my injector duty cycles to go through the roof and needed a fix. I was running twin Magnafuel 4303 pumps (which flow a ton more fuel than his triple set up) with a 212lb injectors. Because the the fuel press was not moving 1:1 with boost it was an indication that I didn't have enough pump. That indication was stupid cause twin 4303's can flow 4.5-5.0 lbs of fuel a minute. One I figured out why, my IDC's came back to a usable level, potentially saving the motor.
Just giving a little tech info from real world experience and not retyping some bullshit I read on the internet like most do.
