Default Wastgate boost vs EBC Control WOT pull 3rd

I need help / advice / educating on whats happening in these logs attached.

I did 2 WOT pulls in 3rd, one the low boost log with 100% across the chart on my Boost Control 1 chart (I think this should be my wastgate )and the other high boost log with adjustments to 90% on cells after 3000rpm to create a leak for more boost.

1) can't understand why the psi is 11.6 in third on the wastgate only, seems high to me on my Garrett FM2 set up, I was expecting 8psi.

2) can't understand why its marginally lower with EBC creating a leak.

Any help would be fantastic, thanks.........

Pipe from inlet manifold just after throttle body to in car boost Guage and MSQ (teed)

Pipe from opposite 2nd cylinder on inlet manifold to BOV

Pipe from wastgate to middle port on my diy autotune EBC

Pipe from turbo outlet to lower port on the EBC
EBC wired to MSQ with switch on dash for high and low boost settings. Switch works as turns green when on high and changes when on low.

Just done a PSI leak test on the wastgate with a bike pump. Rod moves at about 8psi, no leaks when held at 20psi. Used the pipe that leads out of the EBC to the wastgate.
