Are you sure you are spinning at the line? I struggled a few years ago right where you are at. I was running 7.10s and really, really wanted a 6 second pass.

Turned out, I wasn't spinning. I was hooking okay, I just needed more hit at the line.

Called PTC and upped the converter to about 4,000 and BOOM, I knocked a full .10 off the 60 and the E.T. I went from low 1.6s and 7.10s to 1.5 flat and 6.9s.

Now I have a lot more trouble hooking up than before.
