idk but on my s2000 i loved hitting the 2 step launch control. i had my wastegate dump right through the hood...so when you built up boost and dumped fuel into the exhaust manifold, 3 foot flames would shoot out of the hood and make a crazy exploding noise!
just be careful with the heat generated from 2 step, it will warp exhaust valves pretty quickly.
i installed mine 2 weeks ago. i am using stock plug wires. i haven't had any problems with the unit. it works perfectly. i have put around 3-400 miles on it. just follow the directions for the install.
