APS TT Tune on Automatic 350Z

Another local customer of ours brought us his automatic Rev-up 350Z with the APS twin turbo kit already installed. Although he had previously been using the Haltech EMS, he gave us a visit for our tuning expertise.

With this being a car that gets daily driven for most of the year, we wanted to clean up any drivability issues and make as much reliable power as possible on our Dyno Dynamics. Despite using the automatic transmission, a TransGo valve body upgrade kit had been installed to help with shifting at these power levels.

This particular car utilized the newest public version of the Haltech software, which we have been privately testing on shop cars in previous weeks. Despite some initial hurdles from the new software, specific only to automatic models, our unmatched Haltech experience allowed us to produce nearly 390 whp between 9-10 psi. Wheel torque measured near a constant 350 throughout the entire powerband.

Between this much improved flat torque curve and constant power increase with the automatic transmission, this is one great daily driver. The fresh looking Daytona Blue paint is complemented nicely by a new Alliance big brake kit behind the popular Volk SF-Winning wheels. It’s great when the looks match the impressive power.
