We had this lovely Mercedes GLC63 AMG on the dyno today for a bespoke stage 1 tune. the M177 lump is detuned from factory, allowing plenty of scope for tuning, CHECK OUT THE GAINS we achieved!!
Gorgeous Mercedes C43 in for tuning, now packing a much bigger punch from its new stage 1 tune.
Not too many people doing the Bosch MG1 ECUs like this one on a 69 plate BMW M5 comp.
