Learned the issue was who I chose to go with for injectors and pump a long time ago, shortly after I did that swap but still, I didn’t have any issues myself with the 100’s on a stock pump.

You also have to remember that tuning will make a difference. My stock CP3 is handling my 50 HP sticks just fine because my tuning is dialed in. That could be changed to where my stock CP3 won't be able to keep up/hold RP WOT.

I hit this point with my 6.7 swapped 03 because of custom tuning. I have 60 HP sticks on the stock pump. With MM3 tuning getting close to dialed in, I saw the rail pressure drop. Once I saw the rail pressure demand vs actual pump output graphed with UDC Pro, the problem was obvious. The pump couldn't keep up with demand with only 60 HP sticks as the tuning got more dialed in. The 6.7 with twins would take more than what I could feed it. I thought for sure the injectors would have been the limiting factor but in this particular instance, the CP3 ran out of mojo first. I ran it with a another CP3 to verify.

03 3500 QC DRW 4x4 6spd-6.7 Swap w/DPS S475/ported HE351 Twins, Smarty MM3/Calibrated Power tuning, F1 60 HP sticks, Pacbrake PRXB w/5" Flo Pro exhaust
