As many of you know already know, we've been working for quite some time developing and perfecting our PTUNING PnP WMI System. In addition, we've also logged a substantial amount of time on the dyno in the past year or so to bring you the ultimate in WMI.

Having successfully used WMI on our own championship winning, 565whp 93 pump gas, Time Attack Scion tC, we've always been big fans of a properly set up and tuned WMI car.

WMI, when properly implemented and dyno tuned can yield excellent results, especially on an engine like this that is so ridiculously knock limited due to the ultra-high factory compression ratio. WMI is an excellent alternative for FR-S/BRZ owners who do not have readily accessible E85 stations, like us. It's also a better alternative for those who need to leave their cars sitting for months at a time while on deployment, etc.

Extensive dyno testing and tuning with our PTUNING FR-S Turbocharger System yielded solid results. On a 9.5psi tune on straight 93 pump gas we made around 320whp. With the additition of WMI and tuning with our custom PTUNING ECUTek tune, we made an additional 20whp at the same boost level. Aside from being able to run leaner AFR's and more timing, we're able to run more boost. We also managed to crack the 400whp barrier on our Dyno Dynamics Dyno with WMI and 93 pump gas.

WMI allows us to reach MBT timing at boost levels that you would only expect to see when running E50 or higher. What this means to the owner looking for a solution to inconsistent performance on 93 or even crappy 91 pump gas is that you can now expect full power when on track. As everyone knows, heat soak causes power loss, even more so with this engine. The factory ECU uses continous knock feedback to keep your motor in one-piece when you're hammering on your car during hard driving conditions. WMI pulls heat away from the combustion chamber and effectively raises the gas octane rating in the process.

We're still finishing up the PnP wiring harness. We'll put up a new link here to the vendor section when it's all ready to go.
