That 310 WHP is disgusting. Congrats on squeezing that much out of the little turbo. But I do agree with what other people have stated here. I think it'd "feel" better if it had a smoother delivery pattern like in NA.
Let's not lie though...ANYONE would be content with getting anywhere near 310 WHP, including myself. But now that I've driven the RX-8 for a couple years, not sure I'd like it as much if the max power came on so much earlier and then dropped significantly by the time you've hit redline. Sounds like you've cut the redline down by 2500 RPM or so. If you're really better off shifting by 6500 - 7000 now...then you've basically turned this car into a completely different machine from what it used to be. I guess this illustrates how this setup would have been more efficient on the 4 port with its lower redline? Not much use for in calling it a high revving engine anymore. Now it's just "the monster" sponsored in part by the RENESIS, haha.
Anyway, great job on the achievement. (And if you can't tell, I'm just jealous as hell.)

In my opinion you guys are being over critical. You're trying to draw too many conclusion from just a dyno chart. Let me tell you, you will not notice the power drop after 7500. The revs go by waaaaayyyyy to fast. In 1st and 2nd gear I have a very hard time not hitting redline and it sure as hell feels like it pulls the whole way. Boost comes on at 3k and blam you're at 9k. Believe me the car feels like a beast with 290hp, Its gotta be ridiculous at 310.
All I'm saying is before you draw your conclusions take a ride in a well running turbo'd 8. I am very confident you will change your opinion.

Not true, supposedly PTP's dyno chart plummets after 7500 rpms. Although I have not personally seen the chart. I have seen SFR's though, and there's definitely stops making power at 7200. The power drop off is not an issue with the turbo, I suspect its an issue with the exhaust ports not being able to flow enough at high rpms.

I'm willing to bet that most (>85%)of the gains from the TurboXS setup come from stripping the cat and the 3" tubing - not anything to do with the quality of the Y joint or the mufflers. So the cost savings will more than outweigh the couple of HP that this guys custom jobber might lack.

Sorry for the hijacking but can I ask you? What kind of spoiler is that you have on your beautiful 8 ? You have R-magic kit. Is this from R-Magic or MazdaSpeed? I like it a lot.
Thanks in advance.
PS.: Congrats on your 8!
