    Default Boost on a remapped cdti 120 22psi

    Ive had my Vectra remapped for a while now and its running really well. Recently bought torque pro so I can measure odb2 data

    Anyway its showing max boost as 22psi

    Does that seem high? Does anyone know what boost is on an unmapped cdti?

    Just seems high to me screenshot_00002.jpg

    Diesels have a higher boost fiqure than petrol so 22PSI is fine

    How much bhp and ftlb of torque did you end up with? I have the same engine with straight through exhaust no boxes and air filter, which put me upto 134.2 bhp and 242ftlb of torque so interested to see what I can get with a map

    Vehicle : Signum

    22psi is 1.57 bar. Standard boost is 1.3 bar, so a modest increase and within the limits of the GT1729MV which I think is rated at 1.7 bar max in this application.
