W2 408 Dyno results today !

I did not run my headers. I meant to but forgot to grab them . They are 1 7/8 TTI with 3.5 collectors ... the dyno headers are 1 7/8 to 2" step .

The engine seemed to like to run fat .
I would have liked to see a little higher
afr numbers 12.9-13.5ish but Frank felt the engine was happier being on the rich side.
I didnt run the TR because it was getting late and I was getting tired .
I will try it later on a chassis dyno .
