being a tech i should know this but the dealer i went to other than the one i work at says they have no clue cause they dont have any srt-4's... but isnt the boost gauge supposed to read 0 vacuum or psi boost when the car is off and sits for awhile....mine has read 9 inchs of vacuum for a few weeks and i cant remember when i bought my car if it read 0 when i shut it off.... my logic on the thing is this... if ur car is off it cant have vacuum due to no combustion....there for the gauge should be at 0... a kid in college has an srt-4 and he sayed his reads at 0 but i wanna make sure b4 i order a gauge from where i work that this is an actual problem.... this is problem #2 for this car in 3 weeks... 1st one was the multifunction switch for the headlights... thanx in advance... i would know more but turbo cars are new to me and the only ones i work on are pt's and no gauge....

 

its sad when u look on a technician only website made by chrysler and there aint a boost gauge opperation description anywhere for these cars....this site is the service manual.......
