I have a 2005 b5.5 Passat tdi with some turbo issues I have a boost gauge installed and probably some issues in the ecm hardware. Anytime accelerate with wide open throttle the boost gauge shoots up way past 9 psi at max and tops out dang near 22.5-23 psi (kinda scares me tbh) no overboost underboost codes ever set no rich or lean mix from the o2 and overall idle turbo psi is about 3 psi with 27 in-mg the L/H is always 0.9 (used to be 0.6 about 2 years ago anyone got any hunters to know what is going on?
