Tunerzstore.com stopped by with their 6 speed Infiniti G35 sedan for some dyno testing and an Uprev dyno tune. The G35 is outfitted with intake and exhaust performance modifications, and we began with some baseline tests. The stock ECU tune yielded a consistent 210whp on our Dyno Dynamics and was dangerously lean, with air fuel ratio exceeding 15:1 at some points. Next we tested an out-of-the-box tune using Hypertech tuner. The Hypertech tune consistently produced 213whp and improved the air fuel ratio as seen on the comparison dyno chart below. After that we removed the Hypertech and began custom dyno tuning. First steadystate drivability areas of the map were tuned, improving partial throttle feel and fuel economy. We then tuned the full throttle and power areas of the map, including the fuel, ignition and cam timing maps. The final result was 218whp, with gains of 10+whp over Hypertech in some places and 20+whp over the stock ecu tune in places. Check out the dyno charts below to see why it is so important to get your car dyno tuned.
This twin turbo Nissan 350Z was trailered into our Louisville, KY dyno tuning facility from the Chicago, IL area. It features a custom Garrett twin turbo setup and very nice attention to detail. The results were over 500whp on 100 octane fuel limited by injector.
2004 Nissan Titan dyno tuned on Uprev. 20+WHP and 50+TQ gains!
Saturday we had the chance to work on and dyno tune two very nice 350Zs. First, Matt arrived with his silver 2008 Nissan 350Z, powered by a VQ35HR with intake and exhaust. With Uprev pro tuner, Hal was able to improve the drivability through steady state tuning on our Dyno Dynamics, followed by serious horsepower and torque gains by tuning fuel, ignition and both intake and exhaust cams. The result was a 20 horsepower gain, netting 274whp.
While the 2008 350Z was being dyno tuned, Chad arrived from Ohio with his white 2006 ‘panda’ 350Z. It was outfitted with a new Motordyne intake plenum to compliment his intake, headers and exhaust for a free flowing VQ35DE. After the upgrade, it was strapped down to the dyno for the same treatment. The Uprev pro-tuning suite was attached and the ecu calibration was dialed in to Dynosty-spec. The final result was a big gain in power – a very impressive 247whp.
We enjoy repeat business, and in the case of this 350Z it has been 3 years and it came back for a retune with new mods and 104 octane race gas. The finishing touches were dialed in via our Uprev Pro Tuning suite on this beautiful road-race 350Z on our Dyno Dynamics dynamometer. The intake and free-flowing full exhaust worked quite well to achieve 248whp on the custom dyno tuned Osiris reflash and we wish the best luck to him during this season and next as he takes on Nasa Spec Z class.
