It can be done, especially with stock 1G compression. I had no problem dialling in 24psi with a 10:1cr motor before meth. I'm sure I could get 30psi knock-free tune with my compression too. I didn't go any higher at the time because its all I could get out of my cheap mbc. I'll be trying out ECMlinks boost control with an Ingersoll-Rand solenoid. I can't stand MBCs

You can't tune out mechanical problems!!!
