Lambda figures at top end.
Hi folks,
For those that have had their M156s on the dyno what were your top end mixture numbers?
I am seeing about .81 factory and .78 tuned but found that leaning it back a bit gave more power and a cleaner top end.
I my experience NA cars will often hit the best performance at around .85-.84
Anyone had any experience running the M156 at these numbers at the top end?

I see 12.4-12.6 at WOT on my EC "Race" file
13.5 is WAY too lean
13.5 is WAY too lean

AFR we are seeing 11.5 which I think is too rich 12.4 - 12.6 is the target. We got more power from 11.8 and I suspect it will go better as we lean it out back to 12.4/0.84 - 12.6/0.85
