I seen and read up on this company and was curious if anyone out there has ever ran there system for our trucks?
They clam it improves performance but anyone can say that. They sell coils called S.O.S.-Sultans Of Spark ignition coils and a set of Livewires that improved throttle response and cleaner plugs as you can open up your plug gaps an additional .010".

What are your thoughts?

 

I ordered the Screamin' Demon coil pack from them last summer. Their customer service was great and I received the package within like 3-4 days. My engine was running horribly from a cracked PCV vacuum hose, which I replaced when I did the coil, along with new plugs, wires, and O2 sensors. Since all of this was done at the same time, and my truck was stalling and idleing funny, I obviously didn't notice any difference other than the fact my truck ran normal again.

I haven't had any problems with it though. I gapped my plugs to .065" IIRC?
