I would believe so, I dont remember the kit being more than the capacitors and a piggy back chip, and if I remember correctly you could buy the kit in different versions with or without the chip.
I was trying to find info online but unfortunately it was one of those companies that came out in the mid to late 90's and wasnt using the internet to advertise.
I remember seeing the kits advertised in Hot Rod magazine with a claim of "a few simple wire connections and you'll unleash 20 extra horsepower". I think the chip somehow affected timing when it was used.
