Product Introduction

  • This plug and play tuner attaches to two easy to access sensors in the engine bay and works with your factory DME tuning to remap your boost, timing, and fueling for optimal performance and reduced turbo lag. It features a 64mhz processor allowing sensors to be sampled 800 times per second using dedicated 10 bit digital to analog converters, ensuring smooth and powerful performance. The same box automatically detects whether you have an N20, N55, or S55 motor based on the TMAP sensor voltage and adjusts the tuning accordingly.

Power gains on the N20 motor are up to 45 horsepower and 60 torque (35hp and 50tq at the wheels), on the N55 motor are up to 50 horsepower and 65 torque (40hp and 55tq to the wheels), and on the S55 motor up to 60 horsepower and 75 torque (50hp and 60tq to the wheels). 

Installation is very discrete and it quickly removes without a trace when needed. Fuel economy during normal driving is unchanged. Compatible with all driving modes.

    Really Impressed

    Posted by James J. on 2015 Jul 1st

    I was really impressed by the results of this device. Initially I was skeptical about something that would increase horsepower for such a low price. After reading many reviews, I decided to give the product a go, which I am glad I did. I have had a Dyno or anything other than my foot test, and the torque and acceleration seem to be much higher than the factory settings. The lag is reduced tremendously and that feeling of getting jolted back in your seat almost feels as good as my GTR. The best part was that it was simple to install and completed in 30 minutes. Great product!
