Hi,

is it possible to simply fit an adjustable fuel pressure regulator along with a manual boost controller to an EJ205 engine (2004 wrx) to increase power without needing a remap?

I知 wondering it there is an easy way to mimic a remap without actually having a remap (e.g. increase boost and fuelling manually).

Thanks,
Dan

Delete that thread Sir.

I知 curious if it痴 possible. If the ECU has a boost cut, then a voltage clamp circuit could be used on MAP sensor (so ECU never sees above OEM max). Then increase boost and fuelling manually?

Please try this, but remember to film it for us.

Well, if he does it, I hope he tells us the result.

I知 no expert but I think you値l find there is a lot more than just fuel and boost my friend.
Air being the main thing which is controlled by ecu , ignition timing again controlled by ecu and many other factors that relate back to fuel pressure / quality and as for boost if that痴 not precisely managed along with everything else then you will lift the head clean off the block.
