I recently had my b58 rebuilt with a stage 1 from p2uned (900whp capable). Should I upgrade to xtreme or Spool higher flow DI injectors now before I have the new motor put back in the car? I’m still using the stock auto transmission.

At some point if I ever blow the Trans I figure I will go ahead and upgrade to a pure stage 2 transmission and an even bigger full frame top mount turbo kit, but for now I’m hoping my tuner can just restrict my torque level to push my current big turbo and built motor only setup as far as possible without breaking anything else or throwing a ton more money and parts into the car right away. Any suggestions?
