Why do you want an ignition box atall?
If the enswer is something other than boost or juice it is likely a waste of money, the 96-7 cars especially had good strong ignitions stock.
The regular MSD stuff will nickle and dime you to death because everything has to be added on. IF you are going to be running nitrous or boost and an aftermarket ignition will be of benefit consider the digital or the Mallory 685, both have lots of features all in one package.

I have the 6A. in my 96 TA. I love the box it wasent to expensive. I dont care what anyone says. I put it in my car as soon as i bought it with 113k miles and it has been on there ever since! I have had no ignition failures at all! I get 25.5 MPG with the box and 19-20 with out. Im not saying go out and get it because it will do the same for you. But i have been using it ever since i could drive.

We have all been convinced something useless was great at one point. One of the first things I did to my car was an ignition box and I was smart enough to eventually realize it was a mistake. For maybe a year though I swore it was great.
Last spring I put an Accel 300+ on my car because I wanted a rev limiter and got this box cheap, noticed no difference in the car atall with the box, if a car like mine does not gain from it a stock car is extremely unlikely to.
If the gain did really happen I would guess the plugs were gapped too wide or dirty in which case replacing the plugs with ones gapped right would be the true fix.

if you're juicing later on, look into a digital 6...there will be alot of people who will say the mallory 685, but i just dont like mallory, so i went with proven msd

I have been running the 6la for years in different vehicles and i know for shore it makes a difference in power and fuel economy from the stock in-line 6 in both my jeeps to an old 66 mustang, my 91 and 92 camaro's and my 97 TA. It's not a big difference when you put it on and you may not notice it at all but you will if you take it off after running if for a while. But i would look into something digital with more fetchers

NIETHER!!
I vote Mallory 685. MSD is over priced. The digital 6 box is nice but cost more than the mallory and if you take the time to compare units and prices, the Mallory is a complete no brainer.
I would get a digital box. Why waste time with old stuff that costs a bunch. Get a new digital box for close to the same price (the 685 box)....

I just put a Digital 6 on mine and it made a huge difference in drivability. It's much smoother and responsive at lower RPM. I'm running a little over 12:1 compression and had a light load, low RPM miss. It's gone! I'm sure gapping the plugs at .035" instead of .050" may have helped, but I doubt it would have made the same gain in drivability. Plus, now I get a real rev limiter.
The real test will be when I get it re-inspected. I failed HC by a very small amount, indicating a slight miss.

You need to redo that testing.

I currently have the TR55's gapped at .050. I'm thinking they should be more in .040" range.
