turbo isn't really based on revs mate, its more to do with acceleration...
however, its usually around 3000rpm at full throttle
as for the boost, its standard, but i can only estimate from the boost gauge as it won't be entirely accurate
1st - 8psi
2nd - 8psi
3rd - 10psi
4th - 10psi
5th - 12psi
again, these are just estimates
