I'm pretty sure it has the same knock sensor has the VIII. But I think the IX ECU has better knock control.

I'd say you're safe @ 22psi.
Of course - you should datalog to see what your timing looks like. If you can check your knock sum.

i have a defi gauge..mbc and ecuflash tune i will see 24psi spikes..holds to 20 or so at redline (this is probably more like 23 or so to 19 since the defi reads high)...my car was dyno tuned for this. as stated above too much boost and you will get throttle cut to prevent engine damage
