i installed my mech. boost gauge tonight and after 5lbs of boost it reads extremely erratic. also i never see 12lbs only 8-9 when its readable. i didnt use the line provided tho i used vaccum hose could that cause it?

 

what line you tap in too?

 

Pic of where you tapped into?

 

its in the how to forum.... its the long one that runs by the injectors

 

picture. need to see if you tapped into the right vacuum line

you need to use the line provided. vacuum hose will flex and distort the readings. the line provided (acrylic?) does not flex, and shows consistent and correct numbers.

 

I will never understand why people change to these...

 

i did because my stock one broke...and its more accurate anyway

 

my stock 1 **** the bed so now im going to mechanical ...pics of line

 

 

well i just got back from the midwest eco meet so ill take some in a lil bit

 

the stock gauge is slow and has a lagto it (just like all the other gauges on the cluster). With my mechanical gauge, i can tap the gas very fast, and have my gauge show 5psi before the engine even makes a sound. I'll make a vid some time if you like...
i hit peak boost at any RPM instantly...and my gauge can actually show it. Thats all it is really
I can do a -20inHg to 10PSI to -20inHg probably faster than your gauge will show you getting to 10PSI

Just some info
Oh, they also look badass

 

pics as requested



i switched to the line provided and it didnt change this is a 30 dollar equis boost gauge think its just a chepo and dont work well?

 

thats not where i tapped my boost gauge off of. i cut the vacuum line coming off of the intake manifold and put a "T" in it and ran my boost gauge hose from there

 

you know joshua!

 

yep, gotta T that ****

 

here is were i tap my T at

 

thats were mine is tapped in to just hard to see in my picture... line comes out from under the cover and into the censor
