Review on 🚀 Enhance Fuel Efficiency & Boost MPG: Cutting-Edge Performance Chip/Power Programmer for Mercedes-Benz ML-Class 2.1L-6.3L Engines by Mario Hernandez

. I have a 1999 Mercedes Benz ML320 with over 287,000 miles on it. I asked my mechanic to install this programmer on my ML. This coupled with new "cats", front and rear O2 sensors, 12 new Irridium Bosch connectors, new OEM cables and new MB coils and this thing is a "BEAST"! I just cleaned ML350 and BMW 328i E46. This confused them, especially the owner of the 328i. Of course I also have a real double exhaust. I had removed the stock MB single muffler and as my ML has 4 Kats, 4 O2 sensors and twin pipes leading into one muffler, my muffler shop also added 2 "Flow Master" mufflers in the rear for a true dual exhaust. When this Mercedes 3.2 liter V6 revs up to 6000 rpm, it sounds like a small block Chevy! That's okay. Highly recommended! I would love to try this on an ML500 AMG! OH!
