There is simply no other tune for the S65, and no other tuner we'll use for race calibrations on BMW track cars. Randy Mueller, the wizard behind Epic, tunes these cars in the harshest conditions for actual race teams. All of his experience trickles down to these dynamic tunes that are at home on the street but shine on the track.
Lap after lap power, 8500rpm redline with peak power at redline... With the right accompanying modifications from Macht Schnell, which you can order right here, you're looking at a solid 390-400whp on a Dynojet.
We've worked closely with Epic to spec this tune for the exact setup on our record-breaking E92. Whether you're coming from a stock engine or swapping from an inferior tune, we guarantee you'll feel the difference and see it in your lap times.
RACE TUNE
If you're going to the track, even once a year, you want the race tune. We can option to 8600rpm on healthy motors, but most of all, some of the functions are disabled, as well as certain thresholds altered to keep the engine happy and making power more consistently in a race environment.
STREET TUNE
Not going to the track but want to unleash the full potential of your S65 with the best calibration on the market? Here you go. All factory features and thresholds are kept in place for a like-stock operation, just with a massive bump in power and torque and exceptional driving characteristics that were missing from the M3 off the assembly line. No CEL's.
