AFR check after new turbo

Ok Iím too lean upper 13- low 14 AFR

When I first crack the throttle or rev the engine it goes lean to 14.5 for a couple seconds. Is this normal or something I can adjust?

Cold 1.9. Not totally cold. 80 degrees out and drove it about an hour before. So Brianís setting of 1.7 is probably correct.

Warm 3.55 lower than the 3.65 on the paper

1.0 bar boost 2.6. Slightly higher than the 2.5 on Brianís paper.

When I closed the valve the pressure went to about 90psi or 6 bar. Not 100 psi.
Turned the pumps off and it dropped to 2.2 bar and did not hold for more than 30 min. Started to bleed off.
Bad check valve?
