Have you tried removing the reference resistor or R16/1? I did and let me tell you, it's worth your time giving it a try! Nitrous may be a quick way to increase horsepower, but I'm not going there with my 2.6....just removing the reference resistor has helped performance and fuel milage of my benz!

What kind of plugs are you running? I use Autolite 104 and they are awesome!! When I bought the car it had a blown head gasket from bosch dual tip plugs that the independent car dealer installed. I have been using autolite plugs for over 15 years and I love them. Good luck with your "bullet-proof" 2.6!
