AFR's mega rich after ic change and breather mod.
Struggling to get my head round this,
AFR'A were fine and recently got a new breadbin double ic.
Main jet:1.2
2nd:1.2
Ac: was at 1.1 so increased it to 1.2.
There was a slight change from 11@wot to 11.5@wot so upped to 1.3
When im driving it like a normal car and change up a little early, the afr keeps dropping and staying on 10
The turbo starts fluttering after 10-14psi
I have a standard 1.25 ac to try but whats the 10 AFR all about?
Ill upload a video when I get home

Hi James,
"I think" it was my Pipercross Air filter!
the sponge on the inside had totally deteriorated, crumbling.
Found residue in the venturi.
