Vette(s): My c4 1990 is a euro model in pearlescent white with steel blue leather power seats I have own her for just under 4 years
Can i have some options from you fellow owners as to what would be the best base idle speed to set my L98 90 at. I have been inform that the company that rebuilt it fitted a mild cam and put there own chip in. She is set at 6 dec BTDC at the this time and idles at round 700/750 rpm in gear drops down in stages to that from around 1000/1100
