My horsepower is BACK!!!!!!
Mercedes Benz of Sugarland solved my horsepower loss in less than 4 hours!!! The other dealership had the car a total of 5 weeks and was unable to solve the problem.
It was a completely NON FUNCTIONAL intercooler pump. (To all those who said it was a bad IC pump,,,,,,pat yourself on the back.) They said it wasn't working AT ALL.........no movement. The intake temperatures under load were over 200F. Why the other dealership could not figure this out is BEYOND ME..........especially since I suggested that the IC pump may be bad EVERY TIME I TOOK IT IN.
I took it to the track again..........first run.........2500 feet density altitude.....12.7 @ 114.5 MPH.
The beast is back!!!!

btw, you need to go back to the other dealer and let them know how poorly their service dept handled the entire situation. maybe you should burn down their new location!

And I agree with chiromonkey...I'd take your timeslips, go get a dyno, and ram those documents up your other dealers'...er...nose!
