Any one use the msd 7 or 8?

For me this is a long term build. I have about 5K sitting on top of the china wall, so almost 1K to make sure that engine stays alive is well worth the cost. Not to mention i get all the features i want.

User adjustable.
Boost retard.
Start retard.
Gear change retard.
Traction control.
Data logging.
3 RPM linits.
And much more.

My plan is to have the car rewired with the new engine in by june? After that i will definitely post on thow the new ignition system works.
