Spent the day dialling in this E92 335i on the new Mainline chassis dyno. Came in with a flat spot in the mid-range and a tune that was never quite finished.
We went back to basics — verified the fuel system could support the target, logged it properly, then built the calibration up from there on E85. The result is clean fuelling top to bottom, sharper throttle response and a power curve that actually matches the hardware.
If your car has a tune that 'mostly works' but never felt right, this is exactly the kind of job we like getting our hands on.
