You shouldn't be running out of fuel with your listed setup. I would check your settings on the MAF-T. If you have it zeroed out, that may be your problem. I had to play with it for a little while to get it just right. If your chip is calibrated for the injectors you have, you may need to adjust the base setting on the translator accordingly.

It's kinda hard to tell exactly what is going on without the use of a wideband.
