Yes theyre both correct.

The STD ECU runs 4psi till approx 3000rpm and 7psi thereafter...

I would not run any higher than 7psi on a STD engine, without an intercooler as its quite close to the DET limit with its high compression,etc.

[rollin on 13's]

i believe its 4 psi up until 4500rpm then the soloniod changes it to 7 psi for the remaining rev range.

they done this to pro long the life of the gearbox as the box is standard.

to be honest i would run much more boost without an intercooler or decent ignition system, these types of engines arn't as straight forward as turning the boost up even thou it ccan be fun but could cost alot of money. Simple ways to lower the compression or the cheapest shall i say would be to take away some of the chamber in the head. or fitting and intercooler will allow you to turn boost up few psi.
take into account all the other stuff though, ie what clutch set up are you using.

ok

for the moment my engine is stock

but i think buy a piece in the head of the chamber to reduce the compression, and to take a big pressure and buy an intercooler

Thanks for your help !
