my boost guage reads 1psi lower acvcording to my ecu via the laptop
guage reads 15psi whern laptop sees 14.1 psi
my turbo si struggling as well, since cold waether spikes at 23 and holds 17 but it is a T25
its probs that your boost gauge under reads.
the ecu sees the actual pressure in the manifold..
the postion of the sensor shouldnt matter as the whole manifold is under the same pressure.
