It's time to get the c43 tuned and of course I'd rather stay local and go to Ecu program but been reading on other c43 forums that Ecu program uses tunes from Poland and they have bricked some Ecus before.
I take it with a grain of salt cause the forum is mainly run by AMR which tunes alot of Mercs in the state's so I'm a bit conflicted. AMR has better hp figures but it's almost double the price
Thoughts and experiences with Ecu program?
