Ron dropped his gorgeous 2012 370z Roadster equipped with a Stillen Supercharger kit and several other goodies. We will be performing some aftermarket maintenance and perfecting the tuning that resides on it. Stay tuned...

Ron’s car started out with 385 HP and 289 Torque at 7.1 psi and was rich off throttle. This was soon fixed.


After Jason finished his tuning via Stillen’s Uprev software, Ron left with better AFR’s all around, more fuel economy, and 457 HP and 336 Torque at just 7.1 psi.
