We instead setup on our turbo cars a surge tank system with a larger pump to avoid problems with the fuel pump and returnless system on the lancers - this way we used the stock pump to fill up the surge tank, setup a return line system and then fed it back to the petrol tank. Worked a treat.

This will have the effect of increasing the accelerator pump values and feeding more fuel, with the emanage able to recalibrate normal fuel curves back to the equivelent 240cc injector size. Something we will be testing on the Ralliart model in its effectiveness.
