I've been telling people that the pump works but some members think I'm full of S**T. I've been told my car is just messed up because NO ONE RUNS LEAN WITH A 181 or 185 yadayadayada. Others working on another solution, have requested data logs because they don't believe in this solution. I don't sell the pump so I have nothing to gain. I am simply trying to help others out like SLK32Germany helped me. This fuel issue has been going on for quite some time and I solved my fuel issues along time ago. SLK32Germany, with the help of AMG tuners in Germany, using the SL55 pump has also solved his fueling problem. Being that AMG, the original builders of the car, solved the problem using the SL55 fuel pump, why are so many of you resistant to this simple solution?
