Hey I just installed an inline fuel pump that'll give me higher fuel pressure. Will I need to have the PCM retuned?

Thanks

yes, in the stickies there's an injector spreadsheet that will give you the new IFR configuration based on the new fuel pressure.

What About New Fuel Rails?

If the fuel pressure measured at the rails is any different from when it was tuned (whether it's a new fuel pump or new rails or new injectors), then yes the tune will be off. I'm not saying new rails will change the fuel pressure. That's something you have to measure with a guage...
