Sounds like a waste of time and money.

I don't see any reason to assume that the Toyota engineers messed up in that department. The only evidence presented is the one dyno chart without any explanation of test procedures, independent audits, etc. Run a few cars through dyno tests and you're bound to get enough run-to-run variation to be able to pick out one result that makes your product look good. And the one they show looks suspect to me. Look at the curves right at the power peak around 6800 rpm. The HP curves show a gain from about 280HP to maybe 295HP or about 5% - not bad, but nothing to get too excited about. BUT, look at the torque curves at that same 6800 rpm. They're lying almost right on top of each other - no 5% gain there. HP and torque at the same rpm must show exactly the same percentage change. If the torques are the same at 6800 rpm then the HP numbers must also be the same at that rpm. So something's fishy with the one chart they show.

If you want a bigger spark the only way I can think of doing that is to have more windings on the seconday on the coil."Ultra Fast Multi Spark Discharge". Could not figure this out.Assuming that the Toyota spark is designed for the best possible combiustion I cannot see how this could help.Of course someone could try it out and post back the results. I liked the scope pics LOL.

Seems very pricey for the return
