If Jay's dyno chart is from 3 to 4 years ago when he had S2 cams(?), and no
JWT ECU, but 18* of  timing advance, could the problem be with the overly
advanced timing causing the drop in torque?
Much the same as was seen with the S4 cams before JWT changed the program for
that cam specifically?

An educated WAG...
