I couldn't care less if people think they're chav or not...
I run a 21-year old Porsche Turbo. I also have a MkIV Golf which I bolted a Supercharger on to... -Over the years these have had plenty of issues.
Nonoe of the issues have been insurmountable however, but without a boost gauge, and the familiarity with the readings which it should give under CORRECT operation, both of these cars would have been MUCH more difficult to keep in perfect running condition.
Lit up with neon, in a pillar-pod... yeah, that's a bit chavvy for sure... but tucked discretely away where it just looks factory-ish... not so much chav as functional.
So far, almost 30,000 miles and NO worries. -But by now I'm completely familiar with how it's SUPPOSED to dance, and if anything ever DOES go wrong (like the infamous diverter valve failure) I've no doubt that I'll have a much better idea of what's going on.
