Could this be a fueling issue? Hope all is well LS1tech peoples!
When the car was on the engine dyno back 2017 it had a 255 pump and we noticed a fuel pressure drop below 58psi at 4,000 rpms. I've since installed a Walbro 450 in the tank and I'm still using a C5 fuel filter/regulator setup but am beginning to think that the fuel pump wasn't the issue to begin with. Right or Wrong?
