V3 - 6. To a certain degree the 7-8 are the same but from around 21psi... V9 & 10 of course not having forged internals I wouldn't run more than 18 on without supporting equipment, (uprated sensors, reflash, etc).
With the later models the ECU's are somewhat self learning and have the ability to self adjust maps within reason, but they only have a limited range before things start getting hazardous.
You've got to remember that Factory MAP sensors in the older cars only have a 2.3Bar absolute range, so that's 1.3Bar of artificial pressure, the other 1 bar being natural air pressure (or 0psi boost), the sensors start to read from absolute vacuum...
You may or may not have troubles with turning the boost up higher than the sensors can read, but I wouldn't unless I'm trying to kill a engine!
My version 4 map sensor happily reads upto 1.5 bar - and yes its original
same here, works to 22psi on the link before it maxes out
