 Post subject: Boost Compensation Multipliers-Do I change them or not??

Hi All,

I recently replaced my TD04 turbo in the Forester with an STI VF41 .
I have changed the "pill orifice" in the boost control line with the correct STi Forester one from japan and have changed all my wastegate duties and compensations etc to the Forester STI tables to ensure correct boost control for the VF41 turbo.
What I would like to know is if I should keep the Boost multiplier and offset the same as the original tables for my car or use the tables from the STI Forester.
Are these values purely a function of ECU calculation or do they take into account the specific turbo fitted ?...I am guessing the latter.

Are you talking about the MAP sensor scaling? If so, unless you changed out the stock MAP sensor, no.
