This Nissan 350Z came to us from Nashville TN for a dyno tune after installing a Boosted Performance turbo kit, and left with over 400 horsepower at the wheels. A Precision Turbo billet CEA 6266 turbo was chosen with .81ar exhaust housing, and was installed on the factory headers with a 3″ exhaust system. After installing the kit, the team at Dynosty was contacted to supply a base Haltech ECU calibration in order to drive the vehicle to Louisville for a complete dyno tune. Upon arrival, Hal quickly dialed in the drivability and began working on power tuning. 300+whp was achieved and some minor changes were needed to get the boost controller working. After the adjustments we were able to post up consistent 400+whp numbers, ending at 417WHP max at 9-10psi. This is great power for the stock VQ35DE Nissan 350Z engine with Boosted Performance turbo kit on stock headers. Generally we recommend aftermarket headers due to the stock headers restrictive nature for 400+ territory.
