Is the car is standard e.g no remap you boost figures should be from 5-10psi in 1st-3rd, then drop to about 5psi in 4th-5th.
Stage 1 remap would normall see around 15-20
And stage 3 is about 30.
Now it is normal if your say in 2nd and your boost might fly up to about 11 then drop to a steady 5.
Don't quote me on this thou
