After a few weeks of research on the "best" boost gauge with a strong bias for clean integration with the factory color scheme, I purchased a MadDad for my '09 WRX. So I got it installed yesterday, which would have been admittedly easy sans my typical bad luck, e.g. defective fuse tap = lots of wasted time. As most of you know, the MadDad is an electric gauge but it seems kind of bouncy during boost. Is this normal? To be honest, this is my first car with turbo, hence the first boost gauge I've had, so I have nothing to compare it to aside from the factory gauges.
Overall, the gauge seems to operate as expected except for the somewhat jerky operation. It does the sweeping action smoothly and on vacuum it is relatively smooth but it doesn't seem to give a very accurate/smooth reading anything in boost territory. Also, I calibrated the gauge as the directions instructed.
