well i believe they send multiple sparks to each cylinder instead of 1 and depending on wat one you get u can set a different rev limiter and also a 2 step

Almost no advantages at your performance level. A spark based rev limiter is nice to have but not necessary on mild setups.

In the 70s and 80s stock ignitions were weak and left room for improvement, by the mid 90s though they were looking hard for idle emmisions improvement and 100K mile tuneup intervals so ignitions of the 90s and later leave little room for improvement.

True, as said they create multiple sparks under 3K rpm and they "say" it increaces fuel mileage. I didn't see a difference and if your worried about fuel mileage your probably shouldn't be trying to make the car faster! On our setups (somthing like yours or mine) I didn't notice a difference and I doubt you would. I use it for the peace of mind of a decent rev limmiter in case of missed shifts and I have a 2 step to make launches more consistant.

I just hooked my box up a few days ago and I really haven't noticed any difference. Only advantage it gave me was it made it simple to connect my shift light and adjust my rev limit.
