If it reads Lambda 1.0 when you're on boost - worry

Ideally it needs to be in the 0.7's on boost

Doesn't sound too bad, get it checked out by someone who knows what they are doing though!

What gauge? i use a G3 with the dial

The wiring on these NEED to be perfect!! 12's on low boost is no good needs to be in the 10/11's on high boost to be safe at max RPM late 10 imo

What car what set up ?

that seems a tad lean. What sort of boost was that figure at?

check the reading you get on the laptop software against the gauge if it isn't an XD gauge, as ground offsets can have a big effect.
