Thanks so much for the info! I've emailed them.

On a side note , now I'm not sure if it's mapping issues or vct because after plugging in, I'm still hitting boost late at 4k ish. And now car feels heavy at 2-3k rpm.

21u should be all in by 3.5k in 3rd and 4th gear when loaded up.

I was reading through the thread and was going to weigh in anyway, though looks like you're very much on the page I am reading from - so I'll +1 with with a bit more anecdotal evidence to support it

The ATR28SS15 would be a perfect turbo for your application. I didn't look into some thing even smaller as it doesn't make that much of a difference in response but did loses quite a lot of power. I'

Yes felt a bit weird to drive as im used to boost coming on earlier. ..

Has this got anything to do with ebc settings? Back then my "start" setting was at 0 . Now I've used the start settings.

Idk. .. :/

ATR43G3SAT in Ceramic ball bearing is the most responsive one out of all. The TD06SL205 in 10cm is the next and ATR43SS3 is the least, but how ever made the most power.

ATR43G3SAT is a very different turbo to the standard G3 with different wheels and housings all together. Dyno reading shown it is more responsive then a GT3076 or any kinds of a TD06. Below is CBB version, internally gated, on stock manifold, P98 fuel built as a bolton turbo.

I have trailed many other prototypes in similar kind and this particular one is the far best.

Other thing worth mentioning is Tomei cams on RB25det didn't do much good part from adding 250RPM worth of laggier, which I ended up converting it back to stock. and still made 431rwkws.

      RB25DET S1 Into R32 GTS-T Assistance Required!!!

      This is a simple swap when you reuse the RB20 loom and auxiliaries. I run a standalone, but if I remember right, using the RB25 ecu you only have 2 injectors to inverse.  There are many DIY's on this subject online, including this forum.

      Surprisingly the D6000 is only $1999, I'm waiting for the BF/CM sales, and hoping to get one cheaper. D4000 is well priced, still outperforms the 13" SVS PB-3000 and is like 1/2 the price at $1699 RRP. I do watch a fair amount of movies, and listen to EDM, jazz, symphonies, etc. so the lower notes from a subwoofer are always appreciated. The front 8" stage, just doesn't provide you with lively feeling, even though they are pretty bassy for a pair of large bookshelves. Then again, these days it's just playing Wiggles, Blippi and Ms Rachel, another reason the 3m wide cabinet exists, to hide all the audio gear behind it. They used to sit on a nice pair of stands, but as you know, they make good baby traps too.

      Granted, which is a solid reason why I don't have one. My floorstanders are only -2 dB at 22 Hz.  So they're still working down to <20 Hz. Which is no doubt part of the reason why my receiver shits the bed! That Tonewinner would be about double the cost though, so it's not apples and apples. There aren't many AU$1300 subs (that you can buy prebuilt, I'm ignoring what can be achieved by DIYing) that compete.

      -6dB at 22Hz isn't that great, watch the data from the D6000 from REW

      I'll just leave this here. https://www.adelaidespeakers.com/subwoofers.html TL loading, big power. They sound awesome. This is what I would buy if I was going to try to take the bass away from my floorstanders. Just go with the 12".
