A customer brought in his M340i for a dyno session, so we ran a simple stock vs. Stage 1 Bootmod3 comparison.
The result was over 80 lb-ft of torque gained.
Nothing else on the car changed. The tune was the only variable.
If you look closely at the graph, you can see how fuel quality influenced the car’s potential. Consistent fuel quality matters.
Even so, it is impressive how much a Bootmod3 tune can wake the car up.
