Regular boosting and heat helps with these engines.

Yep, 350+ is indeed awesome, but irritating this time of year with excessive wheelspin.  The power delivery is not as smooth as Stage 1 either with necessary dips in boost onset to avoid KO4 surge. Call be boring / hard to please, but the jump from 1 to 2+ isn't spectacular enough to justify the piston ringlands ticking time bomb, or the expense of getting there.  So I'm rolling back to Stage 1 in the spring      310/330 torque is the sweet spot imo for KO4 engines.   2+ makes the engine feel fragile, and that's born out on the facebook group by over tuned engines smashing themselves to bits.

So what your saying is ... I shouldn’t go stage 2+ ... just stick with stage 2 spend on other areas ?

I would be surprised if anyone has regretted fitting an upgraded pump. Even on stage 1 k03 without any pump pressure specific mapping, my car pulls stronger and more smoothly in the midrange after the VIS pump was fitted.

It's up to you mate.  I didn't really notice a big difference between 2+ and lower stages of tune.
