i added a 2nd reg for the nitrous side, i Y off the main feed, and both reg are bypass style. so the 2nd reg that i added wont adjust and only stays or mirrors the engine reg psi. im lost on what to do here now

if you run some sort of return you will prob end up needing 1 bypass reg and 2 deadhead regs.

you can increase pressure high enough on bypass reg to feed 2 deadhead regs like the link suggests

or

put 2 deadhead regs on a fuel log with a bypass reg on the outlet of the fuel log back to the tank.
