I just installed my boost gauge this weekend and it is only showing 5.5 - 6 lbs of boost at WOT. I was under the impression that the S/C should put out in the 7-8 lbs range. But I noticed that when I turn off my engine it reads "-1". I was wondering if the means that everthing will read 1 under where it should?? Because that puts me closer to the correct range. Any way, is there a way to recalibrate this thing??

Or is my charger (1st gen gray) not putting out the proper pressure... :cry:

 

I had the same issue and called TRD. 6psi is the max so you are good to go.

 

yup 6psi on mine also. but you know my first boost gauge got stuck on +4, performaceproducts replaced it after i sent it back.

 

mine goes to 7-8psi...what are you using for the boost source for the gauge? I'm t-ing off the port right off the sc that goes to the fpr.

 

That's the same port I'm using.

Does anyone else's read -1 when the engine is turned off??

 

check out my sig pic...my boost gauge is actually a hair over 0 but still in the white of the 0 marker...I will check today and try to get some pics of WOT and turned off.

 

Mine does. It maxes out at 6 psi. I also have it T'ed at the FPR

 

I'm just wondering that since its at -1 when the engine is off, if that means its reading 1lb less than it should aka 6 = 7. I'm just glad to hear that others are only reading 6lbs.

 

Good question. Mine sat at zero when I bought it and it would only go to 6 lbs. So I assume its still accurate..

 

That is odd. I am getting 10+ on mine...
