nailing it through the gears (close ratio box), boost holds at 0.9 bar to the redline in every gear.
however, if at low revs in 3rd, then plant it, it comes onto boost between 3500 - 4000rpm, and boosts to 1.3 bar, then backs off.
go along in fifth at 4000rpm, boot it, and it holds 1.1bar.

question is, which pressure out of this lot is the boost pressure of my car, if you know what i mean?

thanks

ian ;)

also, would an electronic boost controller, such as the apexi, sort the boost out and keep in a more linear pattern?
