TRZ dogbone installed...boost gauge inaccurate?

[serialtoon]

I installed the TRZ polyurethane motor mount yesterday afternoon and i noticed that my boost gauge sits at about 2 notches up in vac. Before my vac was -23 and now it sits at -21 and when the car is off, it sits right below the 0. I have a ProSport mechanical boost gauge btw. I have a feeling its not reading correctly. I can usually hear the turbo spool up and ive noticed that it starts spooling 2 notches before 0 on the gauge but i have also noticed that i don't boost to 15.5 like im supposed to. More like 14. Anyone else think the gauge is on its way out? Thanks for the response.

These gauges are known to be abit unreliable.

i've seen someone else say the same exact thing with his prosport

Yea, i contacted someone at ProSport and im going to RMA it. ill give you guys some updates.

Have seen the same thing, tap the gauge and it will return to zero. Not the right answer, but it zero's it.

Yea i did that....still lower than than zero. I got a few responses from ProSport and they are going to evaluate the gauge and see if they send me another one. Im shipping it out monday.

Subbing for updates.

Just wanted to ad that I've had some issues with my prosport electronic gauge too, however, I also want to mention they have been very helpful to work with. My needle sits below zero about 2 degrees and so when I go into boost I'm only seeing 13-13.5peak which is frustrating.
I paid $20 for a new sending unit, they are actually going to send me two, I'm still doubtful this will fix the problem since it seems like its the gauge that needs a re-calibration, but it's what they suggested so we'll see if that fixes the problem. I'll let you guys know if does.

Mine reads about 2 psi below in vaccum than what DH displays. I thought that it had something to do with FMIC. But now I realize that I switched back to TRZ from CP-E mount at about the same time I installed the FMIC. So, perhaps, the extra vibrations affect the gauge reading. I doubt the new sender will fix the problem. Possibly a new mounting point for the sender would or an addition of a piece of some vibration dampening material between the sender and the battery box.

sorry about the gauge. Like the dogbone at least?

Yea i cant believe i drove my car around for so long without it. Stock MM is absolutely horrible. As for the boost gauge, i think im just going to buy a different brand.
