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, 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.
