Stock boost gauge??

I just noticed the other day when I floored my car on the boost gauge the very last light or square did not light up.From what im told that this gauge isnt very accurate.The car seems to be performing normally.Any ideas.
P.S. When I fist bought the car all the squares light up upon full throttle.

Get a real gauge. I wouldnt worry about the stock guage.

Ripn how i Can install a mechanical boost gauge??? Do you have any pages or something... i have an autometer mechanical boost gauge wich i wanna install on my 97 GTP.


Thanks

oh,, and a trans temp gauge too... from autometer, i need the wiring diagram for both... if you have please send me...

thanks again...
