| The hot-rod community does it all the time. There are wiring looms and electronics available to fool the computer to not throw a check engine light (emissions). Then, you have to tune it.
I suspect that the ML cat problem stems from using the lowest available grade of gasoline. I used to run premium and switched to mid-grade and all seems well. I am scared to try regular 87 octane as we tried in our Toyota with poor results. I have over 187k on my 98. I have seen cats go early on others and have not been covered under warranty. |
