We've created packages that will allow your base model to make the same horsepower as the 2018 172 hp version or the higher horsepower EVP tunes! 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. With the 2019 fuel pump assembly, we can tune it to the same power as the big brother versions! Over 185 wheel horsepower (230 engine hp) is achievable! 

• Upgrade your 120 HP model to the same horsepower as our 2018-2020 X3-R EVP Tunes!
• Speed limits raised / TQ limits removed in Low Gear
• Low Gear rev limit increased from 8300 to 8600 RPMS (9000 RPMs on big injector and Stage 3R tunes)
• Speed / TQ limits removed in High Gear
• High Gear rev limit increased from 8300 to 8600 RPMS (9000 RPMs on big injector and Stage 3R tunes)
• Engine Speed TQ Limiters removed (“Shaft Saver delete”)
• V-Max Raised
• Improved throttle response in all modes (E-Gas Settings Improved) - Linear throttle rather than the lazy pedal the factory has programmed
• Fans set to activate at 165 degrees
• Race Start – No need to press the brake to start vehicle
• Fueling is corrected for the various stages so no fuel controllers are needed

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

• Stock programming is VERY Docile

NOTE: Some customers have asked for tuning option that does not require an intercooler. While this is possible to make a higher horsepower number for a very short dyno run, the fact is the engine power is limited by intake temperature on pump gas - it is only possible to make elevated power for a couple of seconds before the engine must derate to prevent detonation due to high intake temperatures. It is not worth the risk to do a tune without adding an intercooler.
