I want to say we have tuned that setup to around 17-18 psi. You don't want to take the base map and just crank it up to 18 psi and let it rip, you must start at wastegate pressure and confirm the tune is solid before slowly turning up the boost pressure.

You will be running less boost than you would see on an STi with a similar turbocharger due to the higher compression on your hybrid motor.

Thanks,
Phil

The better option is to tune it conservatively so you can beat on it all you want
