Is there a way to extract more Horse Power out of a 2015 250 PRO XS without doing major mods?

The only way and it is simple although expensive is to unbolt the 250 and replace it with a 300.

How about increasing fuel pressure by .5 to 1psi. Newer fuel injectors do flow less then in the older opti motors by about 2 to 3%.

I've had DBR kit for both 250 and now 300. It is great bolt on power. Your WOT gain is minimal. Maybe 3MPH but what is phenomenal is how you don't lose speed even loaded. My 250 Pro XS would hit 77 WOT with DBR it hit 79 but run 78 with a partner tourney loaded. The 300 has hit 86.5 solo and still tweaking but only slowed down to 84.2 with coangler. The acceleration is better and Dave Bush claims they actually REMOVE lean spots from the programming so exhaust is cooler and cleaner.
Kit increases limiter to 6800 and increases horsepower and torque by 20 and 25 respectively.
Any website for DBR? And of course it voids warranty? I never cared on my motorcycles warranty, so I am curious. And does this void tournament rules?
Don't know about tournament rules. My club allows my 300. Here is website:
