HX40 fuelling

[Clinton]

I recently swapped out my GM-8 for a genuine HX40 with a 16cm housing. I haven't touched the fuel pump and as it's electronic (1998) I'm a little confused how I can add more fuel to the system.

It runs at 3psi boost on highway which I'm happy with, post turbo temp is 350c so about 650f or there about, is this normal?

I'm guessing most are going to say reprogramming ECU but as I'm in Aus, it's not very easy to do here. Is there any other ways to get more fuel in or should the pump be putting in enough fuel anyway?

I'd recommend putting a wideband in there. Then if you have to use a ghetto means to tune you'll at least know where you're at.
