I did the Needswings DCAI on my 2002 SLK32AMG and then the EurocHARGED 65MM PULLEY. tHE AR WAS A TERROR. After the tune the SC dpes not work. It is getting voltage. I have done the K-40 check. Eurocharged seems at a loss to help. Rob from Needswings is trying. Any suggestions, I'd like the power back.
