Three for Thursday! Here are 3 owners that visited Z Car Garage for upgrades so they could Enjoy The Ride. Thomas C was experiencing brake fade/overheating with the Akebono caliper setup on his G37 Sedan. We installed a Stoptech Sport Kit with our favorite SS309 pads:

 

Slotted rotors also help shed heat, before/after shown below:

 

We also UPREV tuned the G now making 291hp/247tq to the wheels:

 

Rich M wanted firmer shifts from his automatic-equipped G37 Coupe. We installed a TransGo shift kit followed by UPREV tuning:

 

TransGO kit:

 

The dyno plot reveals the benefits of UPREV tuning and the TransGo kit. Firmer shifts are evident by the absence of the “loop” (blue curves) seen with OEM automatic-equipped Z/Gs.  Huge peak gains of 20hp/18tq to the wheels and increased area under the curve everywhere means this is power you can feel!

 

Garth J brought his 2003 350z to us for Stoptech lines, 5/16″ plenum spacer and MREV2 lower intake, and new Bridgestone PP S-04 tires:

 

With the intake mods and UPREV tuning Garth’s Z picked up 7hp/5tq to the wheels. More importantly are the mid-range and top-end gains:

How can we help you enjoy your Z or G?

 

Matt found Z Car Garage by referral from a local car wash. He had installed a few bolt-ons and needed a tune so we UPREV’d his 370z. Baseline numbers were 294hp/238tq and after tuning 309hp/253tq:

 

The dyno shows significant gains in hp and tq throughout the entire rev range. We are big fans of UPREV tuning and it consistently works well when optimizing individual mods. We will have more examples this week on both NA and FI cars so stay tuned!

 

Thomas C came in for full 60k mile services and a new exhaust system on his G37 S sedan.

 

The old exhaust system had an aftermarket y-pipe that didn’t significantly increase power. We installed a full cat-back system from Fast Intentions followed by an UPREV tune. Old vs new:

 

The new exhaust looks and sounds great:

 

On the dyno we were impressed with gains from the FI exhaust combined with UPREV tuning. Peak numbers were 302hp/249tq to the wheels, an increase of +15hp/10tq. Check out the mid-range tp redline gains in both hp and tq from 3500rpm:

 

UPREV tuning for your Nissan/Infiniti is one of the best methods for maximizing power gains from bolt-ons. Another nice feature UPREV allows is multiple fuel/tuning maps that can be accessible with a push of your steering wheel mounted Cruise Control buttons.

What if your Z/G is a base model without the fancy steering wheel? Have no fear! Mark G performed a steering wheel/gauge cluster swap on his 2003 350z and created a step-by-step installation guide:

If you are interested in performing this mod yourself please download the entire guide HERE. Thank you Mark!

 

 

Bob F came to us on local dealer Beshoff Infiniti’s recommendation.  His G35 Journey sedan already sported a Borla exhaust, high-flow cats and JWT intakes but it needed tuning.

 

We removed the clip-on ecu to re-learn fuel maps and UPREV tuned with nice gains of 16hp/11tq for a total of 280hp/251tq at the wheels on this automatic-equipped HR engine:
