What is the best first mod for a BMW S58?

The best first mod for your S58 (M3, M4, M2, X3M, X4M) is a high-flow downpipe and a custom Bootmod3 or MHD ECU tune. This unlocks the most power right away, especially with upgraded fuel.

How fast can an S58-powered BMW go 60-130 mph?

With Stage 2 bolt-ons, S58 BMWs can do 60–130 mph in as little as 5.2–5.4 seconds on Dragy (real-world testing). Full single turbo builds see times in the 4-second range.

Does the MTech Performance turbo kit fit all S58 models?

The MTech Performance single turbo kit is a direct fit for G80/G82/G83 M3/M4 models. For other S58 cars, a custom kit can be made—use the Request Quote button for details.

Can I get remote tuning for my BMW S58?

Yes! MTech Performance offers full remote tuning via Bootmod3 or MHD with live support from #TunedByMoose. Track support is available upon request.
