2018 Turbo stock. installed a wideband AFR kit with the sensor in the location I determined accurate, 4″ south of the o2 sensor. Also installed boost gauge. So im 14.6 idle 11.5 WOT and optimal normal driving. All good. But going from WOT to no throttle the guage reads + 20.1 for a few seconds, however the boost instantaly drops to vaccum. Is this normal? Worried I might have a issue were it stops dumping fuel from quick throttle releaese.
