Fitted turbo boost gauge , but what should the readings be? At present at tickover the gauge stays at 15 vacuum, however as you accelerate thru the rev range gauge swings around all over the place.Need to know at what revs what the gauge should read.
your readings will depend on engine porting & which turbo, ecu etc your using. Generally at tickover you\'ll get a negative reading as the turbos arent spinning, you should read approx 0.8 wot on first turbo, 0.4 on change over & 0.8 or.7 on second turbo
