You can use your stock injectors at that power level, but don't plan to go much further (ported heads, bigger cam, etc.) without upgrading. Ideally you'll need to calculate your injector needs though.

I used the stockers with my XE236 for awhile and duty cycle was peaked around 93%.

What if I plan on putting a 150 shot on it, do the injector shoot more fuel for it or will the soleniod be all it needs forit?

Just do injectors now,if your going to tune it tune it once with the correct injector,that way you have room to grow.you will be at 90 plus percent duty cycle and the injector isnt very efficent at that duty cycle.Just went threw this with another member i just tuned,he put 30s in it and was at 75 to 80 % with the 30s.he made 339whp with a cam and long tunes.
