The are different versions of k04s, the one in the mazda, will not hold 23psi at redline, more like 18 if you are lucky

My crappy stock K03s would spike 19.5psi with a GIAC flash before I upgraded to a Stage 3 setup. K04s on race gas could easily do 21psi in the S4 to redline.. But it depended on the tune. But that was like 6 years ago...hard to remember.

23psi...that is probably close to it's peak and sounds about right to me.

That is with two K04s though, not one

I use to own a speed 6, I left the community back in 09 and now have a n55 which is why I am lurking on this thread... anyway, I agree with you that the k04 as of may 09' when I left the speed6, 18psi was about the outer-limit of the turbo with supporting mods. I wouldn't call the car slow by anymeans.. unreliable horsepower ya... sometimes it the car wanted to rip your head off, and other times it was stutter-stutter, and then nothing...
