I don't usually redline the engine and when pushing it, shift around 6k anyhow. So I don't think gaining a few hp between 6-7k will be beneficial to me.
I am probably going to dial down the boost a bit to around 15psi and leave it there. The engine and turbo feels happier there, not being pushed too much.
Should be about 250hp and it's plenty enough power. I'm already spinning 2nd gear, even with my tall gearing. 5spd and 3.9.

next thing you know it will be regurgitated by the n00bs as a definitive fact. no idea why you even mention the experience part. if anything it makes you look bad speculating on a new and untested product.
OP, I think the handful of ponies you'll give up by lowering the pressure will be more than worthwhile by putting much less stress on the little turbo. good idea

we both know this speculation is downright silly, esp since it's been stated (by various people) in at least a few threads now.

What it does is adds low end and mid range torque, zero effect on top end power.
no 2871 for me. 2560 at 15-16 psi is plenty of power.
I'm already spinning 1st and 2nd. Anything more is just overkill and not needed on a miata.

At idle the VVT is in a 'resting' position. As you approach the midrange the VVT moves the cam, more with more load, and by the time you're at 6000rpm the VVT is back in its resting position until redline regardless of load.
Your peak Hp is at an RPM where the VVT has little to no effect.
As a result you won't increase the peak RWHP by 'tuning VVT'.
You follow me?

I think I'd read about this before, but this made it click for me. Certainly explains why the vvt head helps with the 'midrange' then haha.
