Boost readings?

[speedsix]

so you done it then!

how did you get on?

mine readings seem to be like this....

on floor planted....boost shoots up to 25-27psi then drops straight away to around 18 psi and then holds at that...

That's odd, shouldn't be overboosting to 27psi!! More than likely the gauge though.


My car boosts just like this

Your ecu should be requesting around 20psi tops so there is no way it's overboosting to 27.

mine is bog standard at the moment, just installed an autometer guage, its reading -20 on tick over and the boost hits 10 and stays firm at this point until boost stops.


EDIT: Checked pabs guide, 10 should be right for mine...........
