I bought a 2002 MCS a few weeks ago and was aware it had a 15% pulley, Pilo CAI and Borla Street Exhaust.

So, my first performance mod was to get MTH'd. To make a long story short, after keycodes not working and several emails back and forth to Franz, it turns out my car already had the AMD One Click ECU upgrade.

Well, I had already paid my $75.00 for the MTH software so I decided to load it up and see if I could feel a difference. So far, the car seems about the same other than the fact that the DSC does not kick in as easily (a good thing) with the MTH as it did with the AMD.

I am told that the MTH takes several hundred miles to "learn" your driving style, so I will drive hard for this tank of gas and see how it feels in a week or so. I'm hoping for some gains but since the car already had the AMD, I have no baseline to compare it to.

What are your thoughts?
