2015 BMW M3 · S55 · F80

Built to look stock.
Built to go fast.

A fully built S55 running a flex fuel ECUtek tune on a Mosselman oil system with full CSF cooling. Map 1 is 91 low boost. Map 2 is E85 high boost. It looks like it just drove off the lot.

The most dangerous cars are the ones that don't look like it.

This F80 has been through two lives. The first build was a full performance build — fueling, cooling, tune, suspension, all of it done properly. Then it came back to near stock appearance. This time it's getting rebuilt the right way, documented properly, with the exterior finally catching up to what's underneath.

The S55 is a strong engine when you do the work. High-pressure fuel pump, low-pressure fuel pump, EU5 injectors, upgraded charge pipes and downpipes, the full ECUtek stack with a flex fuel tune. The cooling system is comprehensive — Wagner top mount intercooler, full CSF suite, and the Mosselman MSL65-80 oil cooler system that this engine needs when you're pushing real power.

The crank hub is done. The valve cover is done. The reliability work most people skip is done. The only things left are cosmetic — and that's what the current chapter is about.

Map 1 · 91 Octane
Low Boost
Daily driving map on 91. Lower boost pressure, full street manners. Still significantly more power than stock — just not trying to be.
Map 2 · E85
High Boost · ~700whp
Full send on E85. High boost, flex fuel tune, the full cooling system doing its job. This is what everything was built for.
Transmission
xHP Stage 3 Tune
DCT tuned to match the power output. Faster shifts, higher torque limits, revised shift points across all modes.
