Stupid Question # 1

What shouldthe boost gauge be reading @

1) idle
2) normal town driving (not on boost)

Mine seems to be @ -0.5 on idle and between -0.5 and 0 on normal town driving.

At speed I haven't had time to look yet. I still can't believe how much more power the 3r has over my old 355. The Noble would eat it for breakfast on the road and track!

Sounds about right. It should vary more with throttle position (ish) than speed though.

Yep - sounds fine.

The "boost" gauge is actually just a inlet manifold pressure monitor.

All "normal" engines will therefore read -ve as they need to "suck" the air into the manifold from the outside.

Once over 3300rpm you should see it pass the 0 and go to around 0.6ish as the turbos spool up and start "forcing" the air in.
