Good enough for me boss

So, just after the turbo-downpipe joint, on top of the downpipe?

Another quicky for you... Is it possible in your opinion to detect the effect of one cylinder leaning when you are reading the combined AFR from 4 pots?

I guess what I'm really asking is "is it worthwhile buying an AFR meter". I know it caught your failing fuel pump, but that would give a bigger increase in AFR than what I'm getting at

Cheers!
