How much PSI are you boosting?

I currently have Bushar intake and manaul boost controller set to 20.5 to 21 PSI. I peak at 21 and maintain 21 until about 6K then go down to 19PSI.

DAMN! You guys have *****, I am running at the most on my high map 19.5 to 20 psi max and for daily driving 18.5-19 psi with the stock head studs. I plan on replacing them this summer with my 264/272 cams. I run 93 oct daily and 110 every once and a while with the same settings just a leaner fuel map. 12.0 afr daily 10.5-11.0 afr.

I always run 93 octane. I'm running 20psi now. I'm in the process of installing a BR Stg 3. I'm hoping I can push 21-22 once I've got my ECU reflashed.

Ideally I'd like to get a datalogger so I can watch knock and timing. If you're not detonating and your A/F ratios are good, why not run as much boost as possible? Am I wrong?
