Message: [QUOTE="B18B1LS1, post: 1521240, member: 13549"] Still on stock 3.73 gearing. Which I know hurts egt's on the highway in 6th and in lockup. And also obviously makes it slower and works the trans/converter harder. But as far as boost and egt's the gears should be loading the converter harder and adding some rpm which I would think might help more than hurt as long as I'm not lugging it down low. All the shift points are set pretty high to keep the rpms up. 2400 rpm on the highway in 5th should be plenty to stay cool shouldn't it? I've tested for leaks, and I haven't found anything. The compressor cover has a small leak around the circumference when cold, still need to pressure test it warm to see if it seals up 100%. Supposedly the s300's don't use an oring there? Just loaded another tune revision today and added a No Limit intake in hopes of some more airflow. Did a short test drive and so far no real improvement. I'll drive more later this week hopefully.
