Vacuum leaks and tune? My 98 C5 has an olsd tune it now. When it was tuned the car had some really bad vacuum leaks (no o-ring gaskets got swapped to the fast90 when it was installed). Now their all fixed and the car seems rich.
Will an olsd tune adjust itself for that or will it be way off and need touched up?
Also going to a rear tire thats 2.4" shorter, how is this going to change my shift points at wot untill I get it into the tuner.
