I would doubt there would be sufficient fuelling for 21.5 psi (ish).
I would say 18psi (ish) would be towards the upper limit without fuelling mods.
Be careful!

With the original turbo, plus a decat exhaust etc, about 1.2 - 1.25 bar is as high as most TEK'd ones etc are mapped to, I wouldn't aim for more than that. You might make 1.4 with a very well sorted car runnning a standard turbo and an uprated top mount intercooler due to ~2psi less pressure drop across the intercooler.
1.4 is common with a bigger turbo, which will usually be accompanied by an uprated fuel pump and regulator, and quite possibly injectors too.
