Independently proven performance ECU

​Our MS43 performance ECU's have been independently performance tested by a qualified team of performance professionals. Providing detailed comparative analysis against stock performance and competitors products.​

​Unlike some products that are sold online, we don't just copy our maps from some bloke that posted something on the internet. We've taken the time to develop, analyse and test our maps to ensure we deliver a product that actually improves performance without ripping you off.

​Time and time again we see it in our independent dyno tests. Big claims and big prices don't necessarily deliver even reasonable results. Compare the independently tested back to back results against a well known international "BMW tuner" charging more than double the G46 price.
