[DeTomaso] MSD fuel injection

[Justin Greisberg]

I agree 100%!  An out of the box carb (not one of those expensive made-for-my-engine especially) carbs is usually pretty good.  I did EFI because first, in theory, you an do the tuning with your computer rather than taking the carb apart;, and second, because of the intellectual challenge!  Unfortunately, if you listen to this discussion, EFI carries a good bit more frustration inherently.  that' the spirit of the pantera- rather than buy the replacement part online, a lot of us like to engineer a better solution.  When it works, it is very satisfying.  When it doesn't work, I try to remember it is supposed to be fun.
