A little help

[hummin cummins]

I recently did a 24v p-pump swap and installed a street cam and adjustable timing gear and have an issue. The truck runs great until you get in the throddle then it misses at high rpm's and only has only 28 lbs of boost with a usb charger. The pump is timed to 0 and the motor is at 21 deg no bent push rods valves are set @ I-10 and E-20 Starts missing at 2100 rpm's. Afc is set at 15 lbs of boost and it is working. Any ideas

What kind of fuel pressure do you have feeding the pump?

That sounds like your timing is off, or your injectors are to big and your pump cant flow enough fuel for them. What are your mods to this truck by the way?

I got it fixed. I put the wrong size restrictor in the return line on the pump.
Thanks

Was the wrong restrictor too large? Sorry for the dumb question, I'm just trying to learn more about this process swap.

The wrong one was a 5/16's the right one is a 3/16's
