Default Evap leak?

So background i have a 2018 wrx with 8,000 miles.
So I recently changed my fuel pump, did TGV Deletes and egr deletes and got a new tune. Now all a sudden after one day of driving i have a code p0455, p0441. Evap leak. Before i had no problems with a evap leak and now problem i know its not a bad gas cap, but could it actually be a evap. The car holds fuel pressure and its still practically brand new. I dont see how there could be a evap leak. I never touched any of those lines. And my tuner who is very reputable said theres nothing on his end. Any help guys?
Also to add car idols at 71.8% duty cycle and is only at 400pressuere i think that i maybe did a poor job of an install?
