eh, k03 pushin 17-19 psi the way it is should be about all you want to put at it on a daily basis i think...

anyone run 22 every day?

 

you can, only thing is you are gaining far less per psi. You will only see a couple extra whp from it since the iat is getting hotter. Reason is you are already out of the compressors efficiency with a chip and you are moving it further away as you increase psi
