Really sorry guys but I'm honestly not that clued up when it comes to reading my wideband! I'm sure a lot of you probably get sick of hearing the same old questions about afr's etc........ but I have had a look at a number of posts (mostly on the other site that shall not be named!) and some of the responses differ drastically! I understand also that each engine will have a sweet spot (of sorts) and what is right for one car may not necessarily be perfect for another, what I need to know ideally is good and bad extremities of afr readings...
My spec is;
Full T25 on 15/16psi
Breadbin int
Phase 1 fuel pump
Bms d/p
Zeitronix wideband

The boost kicks in at around 2.4k and full boost by around 3.5k

Readings at present are
Idle @14.5
Cruising @13-14
Part boost @10.5
Full boost @14.5

It's this last stat (full boost) that worries me, thought it was quite lean......
Thoughts appreciated gents, and again apologies for the naivety!
