got the car mapped got in it put my foot down gizmo went to 1.2 deffi went to 1.6 i panicked and turned the gizmo to 0.59 which boosts to 1.1 on the deffi, now i spoke the the garage and he said that its mapped off the gizmo and that this is the accurate one and he uses a secondary boost gauge on the rolling road, also the ecu the power fc has a boost cut on it as well so it wont over boost i thought deffis were ment to be one of the most accurate gages so should i believe the deffi or the gizzmo cause god knows i dont wanna be boosting at 1.6bar on standard internals and a ct9 hybrid lol
