Tuning ? 4 Ellis I was surfing this morning & found a thread that says if you are running a boosted referenced regulator, then you need to make the IFR flat. The slope it has normally is to make up for falling fuel pressure as you go WOT. Either that or disconnect the vacuum hose to the regulator.
Now that I have enough fuel pump, this seems reasonable to me. Thoughts?

It would make sense if you no longer have a fuel pressure drop. You now have a regulator and the boost referance ,even one to one, will help with the tuning.
You NEED to get the Wide band on there
We added a TON of fuel to your tables to try and make up for the fuel pump. I would go back to fuel tables you had before the dyno and Start over there
