We are planning on going through Richard's motor to fix some problems and upgrade some parts before he goes back to Denver for the DPC. One of the things we are considering is changing the 9100 cam out in favor of a 9200. Does anyone have back to back experience with both cams or even been around a truck that had a 9200 cam? One of the things we are concerned about is hurting how well the turbos spool. The 9100 cam really brings boost up pretty quick, and when you are at 8000 ft DA, that can make things difficult sometimes. Guy and Lorenzo told us the 9200 would lose some of the spooling characteristics, but they couldn't give us much in the way of exactly how much it would affect it. We don't want to run into an issue where we can't get on top of the chargers.
