So I'm still in the process of using my software to tune...I'm kinda fumbling around now taking my time looking up terms and doing research on all the guages and things I'm able to track. I don't really want to start making adjustments until i have a good understanding of what I'm doing. Fuel pressure reading on my data logger @ idle is between about 43-47psi warmed up..... I replaced the stock pump about 2 months ago with a factory replacement. The car steel feels like it's chugging, is that fuel pressure a conributing factor? is it too high?

If i need to lower it, the only way is to buy an adjustable regulator like the BBK right?

With my mods that I just did (see sig) is it normal to have a little high pressure?

sounds about right to me. the fuel pressure is a little higher than normal b/c of the HOT temps outside
