Ineos Grenadier Performance Tune – by Overland Xtreme (BMW B58)

Unlock the true potential of your Ineos Grenadier with the Overland Xtreme Performance Tune, engineered specifically for the legendary BMW B58 turbocharged powerplant. This tune completely transforms the Grenadier from capable to commanding, delivering a major increase in horsepower and torque while maintaining smooth drivability and everyday reliability.

Whether you're climbing steep grades, towing heavy loads, passing on the highway, or simply looking for a more responsive and thrilling driving experience, this tune delivers the power the Grenadier always deserved.

Real Performance Gains

Our tune is available in two stages, depending on your build and performance goals:

Stage 1 (Stock Hardware Compatible)

Perfect for daily-driven vehicles looking for a strong boost in power without additional modifications.

+90 wheel horsepower

+70 lb-ft of wheel torque

Enjoy quicker throttle response, stronger midrange pull, and a noticeably more aggressive feel throughout the powerband.

Stage 2 (High-Flow Downpipe Required - Available Here)

For those who want maximum output and are ready to upgrade exhaust flow.

+130 wheel horsepower

Stage 2 delivers a dramatic transformation — faster acceleration, increased top-end power, and serious torque for off-road performance and heavy-duty use.
