Rb25Det Slow On Full Throttle

Hi guys, i have a rb25det neo in a r32.

Mods are:

3 inch straight exhaust

Tial gate 7.5psi spring

FMIC

WALBRO pump

Chinese t3/t4 turbo

For some reason, if you slowly ease the throttle on it goes pretty good, Makes good power. But if you just plant your foot, the wastegate screams but but its slower.

On the boost gauge it goes up to 10psi

I have done a compression check and its algood, I have checked the wastegate diaphram and its algood also.

The car doesn't miss at all. I'm thinking it could be a air leak because it will stall sometimes after you come to a stop.

Any ideas guys?

Also because its just the factory ecu with a Larger turbo i'd imagine it would be a problem but my friend has the exact same setup with the factory ecu and it goes really well.
