Tuning Options for OBD1 V8

So I now have a swapped in 360 in replace of the 318, but it seems to be a lil starved for fuel, what can I do to remedy this? Would I be able to just add on a fuel pressure regulator and bump up the pressure?

Your '95 318 fuel pressure regulator is an integral part of the fuel pump, so you can't just replace it with a different one. The '95 pressure is 35 psi. However, the pressure regulators on '96-'98 pumps produce a fuel pressure of 49 psi. If it would fit, and I don't know if it would, swapping in a later model pump/regulator might be what you need. The alternative would be slightly larger fuel injectors.

I don't see why you couldn't just do a bypass and put in an inline fuel pump with a regulator if you want. I know people call it a swampy bypass, i haven't heard of anything wrong with it, plus you end up with a better pump.

What about those with a stock 318 that want to do some tuning?

I want a solution with more adjustability if possible. I was thinking about using the 96-98 Fuel Pump since it has a higher pressure output. 39psi vs 49psi I believe, so I think that might be the difference right there, but I'd like some more finite adjustability.

You can probably add some adjustablility by using a MAP sensor adjuster. This is something that you can build yourself at little expense. They seem to work with OBD1 comuters, but OBD2 computers usually learn their way around them. Do a Google search for "map sensor adjuster".
