It seemed strong in the garage, but when I got it out for it's first easy test drives, it stutters a lot at 4,000 rpm. I was very disappointed and when I stopped for gas and restarted the engine I found a code. It read codes 0171 and 0174 left and right banks lean. I got hold of Edelbrock tech and they said to check everything over to see if it's installed correctly (which it is) and that all the hoses and connections are tight. They also said to uninstall the tune and reinstall it to make sure the Edelbrock Calibration was programmed. It was.

On the next day, the code was gone and I started and stopped the engine several times and the code did not reappear. Then with a little more spirited drive, the code returned.

I called Edelbrock twice and had them call me back. The first guy that called back knew nothing about superchargers. And I never got a call back on the second. The next day I called Edelbrock again and their voicemail says they won't reopen until Monday the 18th. Since the engine is running lean, I'm taking no chances and the car sits in the garage.

Anyone ever had that code after a SC install?
