Fuel injection cheap hp gains

So i recently bought a 13 z400 with 30 hours and a bunch of good sht with it but the engine was stock so i bought a full yoshi rs2 pipe wiseco fuel controller and a uni filter with the air box lid removed with a power lid coming soon. Any way im wondering what i can do with the air intake. On my old kfx it had a 400ex boot and i was wondering if you can do the same thing with a fuel injected model? Or any other little things that may help with a little more power with out opening the engine.

Well it came with a set of mx tires 20x6-10 front and 18x9.5-8 in the rear so i dont wanna go down on the sprocket size. I was thinking cams and maybe trying a 400ex intake boot. Does any one know if you can mod the 400ex intake boot to a efi ltz 400
