I think it probably depends on how you want to use it... I've also
heard people say their truck started better, ran smoother, etc. with
an aftermarket ignition, but I've also seen Bill lose a bracket race
by exactly .2 because he forgot to switch off the MSD after a nitrous run.
I plan to run nitrous someday, so I'm going to get an ignition (probably
MSD6A), but I'm going to wire it up similar to Bill's setup. Due to the
improved smoothness and such, I plan to run the MSD most of the time on
the street, but once I hit the track, that thing will stay off unless I
need the retard feature. (Assuming I get the same decrease in times that
others have experienced; I'll test it first, of course.)
So... I guess the answer is, is it worth it for the track? Probably
not. But if you want it for improved streetability, then maybe...
Depends on how much $170 means to you. :-)
