2.5" exhaust

I think you are correct. Look at the bumpiness of the curve..  timing
was too high. At the time I didn't think to play with the timing on the
dyno. This is back when everyone just cranked their timing and didn't
know better. Geeze is was 4 years ago now, I feel old.

Stock NX2K ECU, and the *original* JWT cams, this was the "street" grind
way before they added "S" anywhere to the name. I think that makes them
the S1's.

The point I was trying to illustrate though was that the bottom of the
curve doesn't look like a cliff as if the car had no bottom end because
of the 2.5" exhaust.
