I've been running the 528mod software all season on high bite clay with the SC boost function on most of the higher settings. This is with 2wd buggy geared 23/78 and 4wd buggy geared 23/78. Both with a 7.5 motor. The delay is set to 4000 rpm and the full throttle delay has been off. The last setting has been at -3 I think. I'm going to play with those settings a little more now that it's about in between indoor and outdoor season. I'll post findings. Motors are usually less than 130 degrees and speedos under 120 (usually way under).
