unless ur runnin a pro tree try lettin off the break as soon as u see the 3rd yellow.
also afx makes a performance computer for automatics. i know there expensive but maybe u can find one used.

And that will generally net you R/T's in the range he is in, unless you're deep staged, in which case you'll have poor E.T.'s to match slightly better R/T's.
Generally, you'll leave somewhere after the 2nd yellow goes off, but before the 3rd yellow comes on. That's about a .250 range. And, it won't help his times any to do so, so getting his launch down is irrelevant to the issue at hand.
Good info on the Auto PCM.
As for the MSD coil, he has it, he might as well use it until it fails. I know people using them with over 50K miles on them. I would say it's no better than the Factory piece, but generally no worse. So if you have it, leave it until it fails. Why spend money that isn't needed?
Again, I recommend new factory style wires. You can get a really good set from Autolite at Advance Auto or Autozone. They're around $29/set, and are of exceptional quality. Come with Dielectric grease already in them, though I recommend a little bit more. That WILL help his performance, as the typical MSD/Crane/Taylor/etc., aftermarket type wire will have a lot of EMI that affects the electronics in the car, and therefore harms the performance generally.
Also, Bosch plugs are notorious for having some issues. A stock set of Champion plugs will run him less than $10. If I were the OP, I'd gap them out to the factory gap though. Most are going to be tighter. You'll want factory gap, + or - .002. Slightly more open will provide a bit more torque generally, as you have a wider flame-front, though it's not exceptionally critical with our combustion chamber design. Neither is indexing, for that matter.
But anyways, those 2 items should help his performance somewhat, and aren't really expensive. Beyond that, he's looking at $$ to increase performance.
We're all crazy, it's just a matter of degree.
