I ran my EVO3 IDM for the first time this past weekend. I had a similar issue (and also tried different clutch settings). In the final qualifier the motor was tuned to around 210+f (when going out), and it got a little soft off the corners almost right away. We spent the remainder of the qualifier experimenting with it. I finally had the pitman put the temp gun down and just richen it until it was too rich, and went forward from there. Ended up back at 190f (88c).

The solution to my problem seemed to be that the motor likes to run under 200f. It had BIG hp there, yet running over 5 minutes with fuel to spare. I'm super happy with mine.
