Big difference. Read the FAQ.

I didn't notice any difference at all.

Me either - other than it is impossible to properly set your timing unless you disconnect it.

Ah, you're right. The difference between the MSD and other ignition upgrades is small. The difference between the stock ignition and the MSD and other upgrades is big. Basically, anything other than stock is good.

I'm talking about from stock.

me too - not trying to start a war on this, but I have noticed nothing from an MSD performance-wise on my car (Mikuni, Streetport 12A, RB dual exhaust, etc., etc.).

It will probably make a difference on a neglected ignition system. If your system is working well you most likely won't notice a difference.

I would still do it over again because the spark from a direct fire is more reliable but be prepared to upgrade your alternator as the MSD takes alot of power.
