Old post just answering because there are 800 people who viewed a question with no answer.

There’s is currently no way to increase hp on the 4xe, nobody has cracked the gpec5 ecu.

Thanks for your answer...
Even with an external power box you think ?

You can raise the boost, but the trans will shift slower to compensate because of torque management.

It’s a worthless endeavor without cracking the ecu.

Increasing boost is fun, I did it in my old 2.0L Subaru WRX and it really brought the car to life. But it puts a lot of strain on a tiny 2.0 engine that is otherwise already straining quite a bit as it is. Personally I wouldn't do it unless you've got room in your budget for a new engine. My Subaru blew its motor as a direct result of playing with the boost after only 37k miles, and I'm not eager to repeat that experience.
