I have the Apexi Electronic Boost and EGT guages and love them. They are super expensive at $350 apiece, and come with only a 30 day warranty, but they look great. I have the white face indiglo ones which match the indiglo gauge faces I have in the cluster. The advanced features - peak hold, warning, and 30 second playback - are great too. I use the peak hold and warning features a lot. I wouldn't want to have gauges that didn't have warning lights...it's a feature that's worth the money in my book. The 30-second playback is real cool too, but I've hardly used that one. One place it has come in handy is recording drag runs to see how much the boost trails off towards redline for the T-25. By correlating it with the pocketlogger data, It helps me to adjust my shifting points to utilize the turbo in its most efficient range.
