There's something holding the car back and it isn't the turbo (unless the turbo is ****ed). This turbo should hit close to 400whp with low boost (under 20psi) without trying, even on pump gas.
What is unbelievable ? GTX3076 vs. DOM3 have the similar compressor and turbine wheel sizes.(76/60) You hit 350 at 16 psi and this car hits 419 at 24 psi with low ignition. Do you think you have TD04 installed on your car? What should be the power difference?

30 psi of boost / 6-7 deg more timing / 11.8-12 afr / high octane fuel should get this car to 500 whp and it is the maximum limit of this turbo.
