18 Challenger, S/C, Fuel System help
Hello,
Have an 18 Challenger with an Edelbrock 2650, built bottom end, cam, ID1050 Injectors. Car ran great but needed more fuel pump. If you look in my tune you will see I added a ton of fuel in the FA table at higher RPM to cover up the pressure drop temporarily until I got the fuel system.
I have now added a Fore dual pump setup with return. Rail pressure sensor is deleted with the kit, fuel pressure regulator is hooked to manifold vacuum/boost.
Car will barely run now and fuel trims are all over the place. Idle characteristics have changed, car runs completely different. Fuel pressure is set at 58psi base.
What am I missing? I figured a little tweaking to tune may be needed but its completely different and Im struggling to get it to run right. Tune from when car ran great with stock fuel system attached.

Any tips or advice is greatly appreciated. Thank you
