2018 120 HP Base Model X3 Upgrade Packages


BRP has given consumers a value priced X3 rated at 120 HP stock.  The drivetrain, turbocharger and injectors are identical to the higher horsepower versions.  This means that with tuning and a few parts, the base model can make the same power as the X3-R, XDS, XRS and XC models.  Here are the items that differentiate the base model from its brothers:

  • Base model does not have an intercooler
  • Utilizes the same fuel pump assembly as the 2017 models
  • Docile programming


EVP has created packages that will allow this base model to make the same horsepower as the the as the 2017 154 hp version or the higher horsepower EVP tunes!  With the 2018 fuel pump assembly, we can tune it to the stock 2018 172 hp, or the extremely potent 2018 EVP tunes!  Over 170 wheel horsepower (212 engine hp) is achievable!

All EVP packages include:

  • OEM 2018 intercooler assembly with fan
  • EVP Silicone Charge Tubes with BOV port
  • ECU Programming to raise the desired power level – 212+ horsepower!
  • (Optional) 2018 fuel pump assembly to run 2018 EVP tunes

There are two options for programming:

  • Send your ECU to 2006 68th Street Suite D Somerset, WI 54025 – we will flash your ECU via the ECU connectors – We do not have to open the ECU!
  • Purchase Maptuner X: Maptuner X is a consumer hand held ECU tuning device similar to many diesel programmers on the market except with more capability. With it, you can program your own ECU via the touch screen interface and included cabling.  The cable plugs into the OEM diagnostic port.    With Maptuner X, you can install the same proven EVP programs.  Not only that, Maptuner X has live datalogging capability (optional).  It is also compatible with most Polaris, BRP and Yamaha vehicles meaning you only need one device to tune many vehicles! (additional tunes must be purchased).  You can return your vehicle back to stock at any time!  Additional tunes can be purchased at special pricing  for the same VIN.

Add 2018 Fuel Pump Assembly

By selecting this option, an 18 fuel pump will be added to the order. This will also change the tuning to the 2018 specifications. For big injector tunes, in order to get the full 18 specs, you must select the wastegate actuator option. For 2018 HP numbers, see 2018 & 2017 with 18 Fuel Pump X3 ECU Programming
