    Im rolling both B58 and EA839. EA839 is sluggish and can definitely benefit from turbo upgrade for better low end torque. For daily B58, I'll say simple stage 2 ecu tune is more than enough. This engine is so smooth and effortless for stock turbo

      @@itsgoofyytaee1110 a bigger turbo will still get you more torque. I have this turbo on my N55, and the spool is so quick, you gett a much better launch. When driving and floor it, by the time the tranny downshifts, you already have boost, so it also pulls hard, I tested this with a SC Camaron 1LE, and he pulled on me for a few secs, but shortly after I put a bus on him before letting go. This was with a stock LPFP, Dorch Stage 2, and an incomplete tune running at only 17psi. You don't lose anything at all vs a small turbo.
      Now that I have a built engine, my tunner says he can get me 870whp with this turbo after I upgrade my fuiling as I still need PI and the LPFP. But that's after the tranny of course, just letting you know of the potential of this turbo, 750 is the factory rated, so you can still get more. Just like this car is rated at 300hp, but look at how much we're getting out of it!
