Looks normal.

Thank you, would going up 2 lbs per rpm point be safe to data log

To me it looks like you are at your limit on adding boost. While you don't have big timing drops, the values are pretty low (ign1 field). If you try moving boost up from here, do it in 1/2 pound increments and re-log. These cars do run on the rich side (AFR field) and yours is no exception. Do you have the fuel wires? I think you will benefit from using them - it will target an AFR in the low 12's. Your is running 11's and 10s.

I'll have the fuel wires delivered today and put them in later. What setting do I enable in the program to have the fuel wires activated?

Optional fuel control wires:

Dyno Test: N54Tech.com - International Turbo Racing Discussion - View Single Post - Infiniti Q50 3.0t VR30DDTT Red Sport and Silver Sport BMS Stage1 JB4

Cliff Notes: Short fuel wire w/ resistor goes in spot 21, long wire goes in spot 20, and both wires then posi-tap to the white signal control wire in the primary o2 sensors. JB4 v6+ firmware required, to enable fuel control set FutureUseD bit0 on.

Options (FUD) bit selections as of v8 firmware:
fud.0 - Enable fuel control wires
fud.1 - Test AFR algorithm
fud.2 - Disable warmup safety
fud.3 - Don't use
fud.4 - Disable over boost, run lean, fuel pressure safety
fud.5 - Disable EWG offset
fud.6 - Vehicle is an RS
fud.7 - Linear pedal input

I don't see FUD but is it safe to say that's under "options" then there are toggles for Bit 0 through Bit 8. So from that enable fud(bit) 0?
