choumbie 0 Posted June 18, 2004 Alrite..Well i just installed my boost and air fuel gauges....Ive got some questions about both of them... The boost gauge...When i accelerate up to about 3000 rpm's or so...is shows that im getting vacuum rather than boost..and then once i floor it and get the RPM's past 3500 or so...is shows some boost...Is this normal to show vacuum like this? At idle, the boost gauge is at about 10 psi vacuum... The air fuel gauge shows the ratio for a moment..and then goes all the way down and then goes all the way back up repeatedly...Can i fix this? AHHH :x help... Quote Share this post Link to post Share on other sites
scruffydubbers 0 Posted June 18, 2004 i think thats normal from a boost guage its only when you floor or part throttle when the return flap will close or partly close giving you the boost from the charger. i beleive you hace to wire in another lamda sensor for the air fuel guage as the one for the engine is constantly changing Quote Share this post Link to post Share on other sites
