Great numbers here from just a tune and catless downpipes on a C190 Mercedes-AMG GT S. The M178 offers plenty of room over the factory tune even on pump fuel. With just shy of 600 lb-ft at the wheels when the turbos spool this thing is going to move.


It would be great to have the baseline overlay but you can see the peak numbers here on the Eurocharged Canada Dynojet in STD correction:


You can get a bit more out of it if you decide to run meth or go to the Eurocharged more aggressive high octane file.

This is a solid every day pump fuel tune.
