    For a truck with heads and headers all the numbers seem pretty low.

    That was at the tailpipe actually ... when I punch it and I am looking at the A/F in the cab from my wideband, it starts at 10.0 and then levels off to about 10.8 up to 100 mph

    Crazy thing is my first totally stock pull on a stock tune was 13.13 , which is probably = to a high 11 A/F in the cab (seems to be 1.5 off at the tip)---
