Our ignition system is pretty well optimized from the factory as it is. We have iridium spark plugs (long lasting, low resistance), each with it's own ignition coil directly attached to it (no plug wires at all).
I emailed ignition solutions and offered to do a before and after dyno of their product if they provided the product "at cost" or significantly reduced cost from retail. In return I was going to give detailed writeups on this forum to help them with their product sales. They never responded, which tells me their customer service sucks at a minimum. At least I could have gotten a "sorry" form letter. I even placed a call into them and their entire sales staff was conveniently in a meeting, with no return phone call I might add. Just something to look out for before you spend 600 bucks on their product.
