What's up guys? I changed my LT 1 over to LS 1 PCM and 24x ignition, not sure about fuel pressure? 43 or 55???? seems to run better at 55. Everything els is LS1 383 forged 11.4 comp, 238/246 605/618 110 comp cam, 195 AFR heads.

I run 58psi base and 1:1 with boost.

You just need to let the PCM know what you are planning to run FP wise, I started at LT1 pressure and ran out of injector.

If you have the 36lbs injectors in your sig I would consider running it on a stock LT1 regulator, rock solid reliable and easier on the fuel pump than high pressure. If it "runs better" at 55psi then the tune is closest at that setting. 36lbs is PLENTY of injector for an NA 383.

If you were marginal on injectors then yeah raising the pressure could resolve that.

The detail oriented guys find a better launch running smallish injectors, raising pressure making the injectors act larger would be contrary to that.
