I have run into a weird situation with my boost guage. I have a Greddy ELectronic boost gauge with peak hold. Recently I notice that my needles just start to go crazy. Like I'll be driving and my boost gauge needle starts to shake and when i floor it it jus go crazy. It doesn't do this all the time just sometimes.

can this be a MBC error? I've had my gauge for a year... and my MBC from Dejon tools for about 6 mtns. It just started to do this recently and I dont know if it's my gauge or something wrong with the boost controller.


Please advise.

Thanks

 

get another boost gauge (cheapest one) and see if it does the same thing.

Also check all the horeses !make sure they are tight

 

my brothers greddy has the small problem.
Somtimes it will just stay at 2 bar.
Were just going to double check the wiring, and go from there

 

sounds like boost leak...yeah check clamps/hoses

 

sounds like its a problem with the boost gauge
not only check the hoses , but also the wire connections

 

anymore inputs on this thread? my gauge is still doing the same thing.

 

if it feels like your car is hitting whatever your MBC is set at then check your wiring.
