If I were upgrading as far as fuel, I would go chip, injectors, lift pump, injection pump, injector lines. Lines really don't make that big of difference without a monster pump. You will starve a monster pump without a lift pump. Injectors on their own won't help, because the ECM isn't programmed to deliver more fuel without a chip. If I was going for mileage, I would put on a higher pressure lift pump and a chip, that's it and keep my foot out of it. Keep your EGT's under 600 and boost under 5 psi with 3.55 diffs you will see 20 or more mpg. If you add power you will take away mileage, there's no ifs ands or buts about it.
