• Comes preset and should require no further adjustments on the part of the person performing the installation

• Features a simple installation with plug-and-play OEM style connectors

• Improved overall rideability and increased horsepower and torque by optimizing stock lean air/fuel ratios and helps cool engine temps as well

Customer Reviews


Installation was simple. Making changes to the settings is simple however, getting the settings correct for the mods on the bike are hit or miss. Have to play with the settings to get it perfect.

Ok easy to installment


This is a great product very easy to install and it made a world of difference on my 950 v star I would recommend this product to any v star rider that has installed a slip on or full exhaust system on there bike. It makes your bike run better and sound better.
