Road Trips

Road Trip DC to NYC

I went to visit my wonderful Nana leaving from NW DC area.  Shockingly i95, i895 were both closed at baltimore.  So we set off again the next day. I went on this trip originally untuned.  Thinking I would just put the car in cruise and chill.  Wow, I was wrong. […]

Force Intercooler Pump to Always Run

While there are conflicting reports about the logic of the intercooler pump.  With mine it didn’t run all the time (you can hear it before she comes up to speed), and with this mod it did.  With this mod you get lower IATs.  Check out here: https://mbworld.org/forums/w212-amg/785054-reduced-iat-s-pump-rewiring.html I’ve heard a […]

Resonator Delete: Make Your Mercedes Sound Awesome

While AMG’s and Brabus sound crazy to begin with, Mercedes engines often have a quiet growl, perhaps especially their V8’s and V12’s.  One way to wake the sound up, especially with the m278 engines, is to delete the center resonators. This produces a nice deep boat like cold start, great […]
