Jim changed his perfectly fine looking stock iridium spark plugs to a new set of stock spark plugs and gained a massive amount of power, maybe that guy had a similar thing happen or he had a bad coil/blow out.
We have dyno tested some of the replacement aftermarket expensive coils, like these
http://www.lethalperformance.com/99-...0ae0dhuk8af750 and the Okadas on Hondas. Changing to a new set of spark plugs gave a measureable gain on both cars, swapping on the new coils after already changing the plugs didn't gain gain any power. We didn't spend all day playing with around with opening up the gap though either. I haven't seen running a bigger gap make a huge difference in power at WOT on turbo cars(we are normally just happy to avoid misfires though), but it does make a difference in idle, cruising and start up.
The SpoolinUp non-CDI kit is definately a nice upgrade for the Evo guys.
