    How accurate is the stock boost gauge?

    I got my ECU back with a stg.2 re-flash and 1st. off I can't believe I waited this long.WOW!! It's like a new car.

    The stock boost gauge won't read more than .1 which is 14.5psi and the tuner said it would be in the 16-17psi range.

    I sware the car feels like it, but the gauge is reading about the same before the flash. The biggest difference is how fast the boost comes on. I have allready forgotten what turbo lag felt like It is the fastest & smoothest boost & I'm lovin it.

    From the accounts I have read, the factory boost guage is not the most accurate unit on the market by any means.
