Don't know if this helps but we're going to piggy back a MSD power grid on our 6AL this year rather than upgrade to a 7.

I don't know about the millijouls or whatever that is but I can switch back and forth between a 6AL and a 7AL box all day long and run the exact same ET. Done it several times clean down to 7 second ET's normally aspirated.
Boosted or Nitrous setups would be a different story.

We did back to back tests this year at Norwalk. Switching to the Analog 7 and coil leaned my Hemi out considerably. ET picked up all the way down the track until the chip hit it. Go for the 7.

That test is inconclusive at best.

+ Sorry to hi jack the thread but the main reason we'll be going to the Grid is 'cause we're also upgrading to a crank trigger. The programmable functions can be found here: http://www.msdignition.com/Products/Igni...oller_Only.aspx
I will post feedback but our season doesn't start 'til May next year
