<x-charset iso-8859-1>OK, you are running too rich at 2500 rpm. I am not an expert on these systems; however, all Bosch FI systems that I have worked on have a mixture adjustment. Find the adjustment and reduce the mixture. I adjusted my Mercedes while it was on the emissions test stand. They were flabbergasted, but they didn't give me any flak. Thomas E.
