You can take advantage of them partially in the tuning process, though. The 460 will require a wiring upgrade to support it. Link to comment Share on other sites More sharing options...

That way you can save for a dedicated anti-surge system, and the 460 can act as a lift pump 1 Link to comment Share on other sites More sharing options...

Yep fits straight into the factory rail, same as the factory reg. Just need to set the base fuel pressure to 4 bar with the vac line disconnected and engine running.Personally I found that gauge was spot on for setting the pressure. Swapping from factory reg and then setting pressure via the gauge, my fuel trims were exactly the same. 1 Link to comment Share on other sites More sharing options...

I was going to get the gfb one, from memory I think this one was on sale at the time or something. Super easy to install, though my base fuel pressure was off when I installed it, I let the tuna fix that 😋 1 Link to comment Share on other sites More sharing options...
