Aaron’s 2018 Infiniti Q50 3.0t Red Sport came to Z Car Garage for bolt-on performance upgrades and dyno tuning. We no longer install customer-supplied parts but made an exception for Aaron as a new client.

He had us install his AMS intakes and exhaust system from GTHaus. AMS air intakes compared to OEM:

 

AMS Air intakes installed:

The GTHaus exhaust system with GTC (electronic valve control), mid and Y-pipe installed. Down pipes are stock:

Aaron loves the aggressive sound from the new exhaust system and ability to quiet it down for cruising. Hear it in action in the video below.

Dyno Tuning

Straight from the factory, the VR30DDTT is an impressive motor, rated at 400 hp and 350 ft-lbs tq in Red Sport trim. With a few bolt-ons and tuning, even more power can be unlocked from the VR30. While were waiting for parts Aaron had the Heat Exchanger installed somewhere else. Unfortunately its very common to improperly bleed these system so it fought us a bit on the dyno. We bled the system correctly to ensure that the heat exchanger could function as we adjusted ignition/fueling curves and of course the boost.

Rob dyno tuned the Q using EcuTek. Baseline power was 325hp/340tq at the wheels. With the AMS parts, exhaust and tuning final numbers were 406hp/434tq, gains of +81hp/94tq! Dyno and exhaust video below:

Enjoying The Boost

With full bolt-ons we installed Aaron was very pleased with the results. This was all done in time for his birthday so we know that he spent the day enjoying the boost in that Majestic White Q50S:

“The car runs great after the tune and new bolt ons. I can tell a lot of care was spent doing the install correctly and testing the tune. It really is a fun car with the Ecutek boost that can double as a daily driver. I will be back soon for some more mods and more power!”

Thank you for your support Aaron! The VR30DDTT is a very cool engine and we are excited to see it with a 6-speed manual in the new Z. We love all things V6 and twin-turbo!
