    I just in ecmlink setting my fuel pressure and I am not sure if I should use the stock 2g 43.5 psi or 37 psi for a 1g. I kept the 6 bolt head and fuel rail which has the 1g fuel pressure regulator still on it. I am also using the stock 1g 450 cc's and a stock 2g fuel pump.

    Yes you'll set that to 37 psi if you have the 5spd 1g regulator. The auto and N/T 1g are 43.5.

    Also every time I set my injector size to 450cc in ecmlink it resets to 483cc. Is there something im missing ?

    Anyone ever wonder why 37? If I would have to choose weird number I would choose 40. How about 43.5? Was that .5 really necessary? I recommend to get adjustable fuel pressure regulator. Black Friday is around the corner. I set mine to 48 by the way.

    It's the imperial unit that makes it seem like a random number. 43.5 psi is essentially 3 bar (2.999) and 37 psi is 2.5 bar
