The reason most stock boost gauges are so bad is because they're run off the ECU, and not an actual boost source. It's what the ECU "thinks" your car is boosting to by looking at an airflow table.
Any boost gauge that connects to a vac source will work just fine. Some are more accurate than others, but being off a psi or 2 won't kill you. Inproper tuning has a much bigger effect than that. The autometers fit nicely in the pillar pods, and are cheap. That's the choice of most budget races. But I'll be using Defi when I actually need one.
