When I look at my stock MR boost gauge, i go into boost at wide open throttle (i peak at 1.3 bar) and when i let off the gas and hit the clutch, i notice it takes about 1 second for it to go all the way to vacume (1 second = long time in this situation).

But looking at alot of videos, i see when people are in boost, and change gears, the boost gauge goes from boost to vacume in 1/100 of a second.. aka REALLY fast. Can anyone explain why this is?

example of REALLY fast boost to vacume transition:

And this video too (holding 1.4 bar very nicely actually)

My question: do i have a homo boost gauge or is that how the stock gauges are?

 

the stock cauges on the evo are crap !

 

time for a real boost gauge, i have a prosport for sale if your interested...

 

cauges.. lawl;

 

it may just depend on the machanics of the gauge. the needle can only move so fast. i dunno the quality of the stock gauge, maybe its just slow on the way down. id say as long as u have no boost issues ur ok imo

 

I have a defi and the stock MR boost gauge they both read the same boost pressure,so the stock gauge is pretty close.

 

Im not worried about if its reading it correctly or not, im just curious to know why the stock gauge is slow to fall back down?
