The Stage 1 tune is designed with factory standard cars in mind. While the tune can be applied to, and benefit from additional vehicle modifications, it’s primarily designed to give a moderate increase in torque and horsepower across the entire RPM range for everyday use. Typical performance increases range from 25 to 30 HP, and 45 to 70 ft.lbs of increased torque. These variation depend on the vehicle model and any additional modifications installed. N14’s generally see the larger increase in HP and N18’s the large torque increase. For the F56 you can expect increases of 65 HP and 90 ft.lbs of torque. Each Stage includes three performance maps so you can pick and choose your power level from daily driver to track toy. Due to the wide range of models in the BMW F & G Series, power gains can range as high as 75 HP and 105 ft.lbs of torque. Feel free to email for specifics regarding your Series.
Various optimizations can also be requested to tailor the Stage 1 to fit your needs. Extra pops and burbles in the exhaust as well as a linear throttle response for better control at the track. Include your request in the notes section. These customization’s will increase the cost of the tune but will not exceed $100. Depending on Stage X Handheld applicability each Stage can include three performance maps so you can pick and choose your power level and the options you want activated.
NOTE: An oil catch can is highly recommended for all levels of tuning. See article Catch Can vs Detonation.
