For those with boost gauge.

Just want to find out at what rpm does our car hit full boost (stock and with procede). I am too lazy to intall a gauge in mine so any info or link will be appreciated.

There is a post showing the procede curve, which I think is around 14psi in < 4000rpm, and around 12psi up to 6500rpm.

Stock is around 6psi < 5000, and around 8psi up to 6500rpm.

or you can see for yourself by hooking up a boost gauge into the vacuum lines that go to the bypass valves. According to my data, v1.2 and up procede maps run just over 13psi in the low end, 11-12 in the midrange, 10-11 up to 6750 and then down sharply to 6-7 by 7000rpm. All this data is viewable and loggable thru the free procede user software.
