Get your Acura NSX Tuned with the worlds first performance Tuning Box kit from VR Tuned.  This kit is specifically designed for the NSX 3.5L V6 twin turbocharged engine.  Having used tuning box kits on cars such as Porsche, McLaren, BMW, Mercedes, and others, these kits will dramatically change the vehicles performance. Available for all markets that sell the NSX under the Acura or Honda brand, this tuning box kit is far superior to ECU tuning. Each tuning box kit is a plug and play solution to boost your vehicles 3.5L V6 twin turbocharged engine making 507PS/503HP.  Combined with 70hp from the electric motors that drive the front wheels, the NSX has a total output of 573HP or 581PS.  With the Tuning Box Kit installed, expect a combined power output of over 650bhp! This kit still allows the electric motors to function unchanged. The multi-channel tuning box kit plugs into the boost sensor, manifold pressure sensor, camshaft sensor to take control of these parameters.  The performance map on the digital tuning box helps drive the power up while still being safe, reliable, and effective.  Because the tuning box is a plug and play device, it can be removed for warranty purposes without any trace from factory diagnostic tools.  Each kit also come with a jumper plug that allows you to put it in a stock mode. 

With pure 91 octane, the gains were very impressive.  With an increase in boost pressure starting out immediately and peaking at around 17.7psi, we see large gains from 3500rpm all the way to the stop of the dyno test.  At 4100rpm we have a gain of 75awhp.  At 5300rpm we keep this gain going with near 65awhp.  Towards the top even where the stock car falls off, we see a gain at 6100rpm of just over 50awhp.  Adding in some octane booster to get around 93 octane which is predominately found from the Midwest to Eastern USA states, results were even higher.  Because of the improved octane, we can also change the dial settings to increase the boost.  Boost is slightly increased to 18.4psi at its peak but mainly follows the other boost curve.  AFR is untouched and still running very safe.  At the same RPMs as above, the car makes near 90awhp at 4100rpm!  Even at 5300rpm the car is still making 75awhp over stock.  Torque is drastically increased as well.  At 3700rpm we see a gain of near 125ft/lbs and this carries strong through the curve.  4900rpm we still have a gain of 100ft/lbs and this tapers down to near 80ft/lbs around 5300rpm.

Vivid Racing has been in business since 2001 and has worked with customers all over the world. In 2005, Vivid Racing got started in the Porsche market with their 2000 Porsche 996 Carrera.

Having had success in the popular tuning chassis' such as the Subaru WRX STI, Mitsubishi EVO, and BMW M3, this was a natural progression of expansion in our repertoire of vehicles.

The diversity of vehicle products and services has allowed Vivid Racing to continue to strive for excellence while maintaining exceptional growth. ECU tuning has always been an extremely important part of modifying and building vehicles. This is essentially the glue that brings the performance out of aftermarket products and packages. With this next stage in the companies footprint, was proudly launched in January 2014.

As the tuning industries tools became more accessible, so has the ability to partner and work with individuals to offer a unique service with added value. Working with several tuning companies over the years, we have experienced the upsides and downsides of the ECU tuning world. As it is our mission to offer unparallelled customer service and support, it is equally important to offer a great product that is tested, convenient to use, and priced within reason for the current demographic. With a Mustang All Wheel Drive Dynamometer in-house at our Gilbert, Arizona facility, we have spent countless hours testing tuned files, the affects of different vehicle modifications, and learning how vehicles react to our changes. But most importantly, our product confidence comes in that we have owned these vehicles, daily driven these vehicles, raced these vehicles, and understand what the consumer is looking for.
