Well I ran the 107 software this weekend, I didnt notice any speed increase over the 110 on our track, but I spent most of my day trying to get the motor back down to a resonable temperature. It was 3-5 degrees in the air with a cold wind-chill and the motor initially was coming off at 80 degrees C.

In the end I ended up with the following:

Punch( DRRS): 4
ATMS: 22.50 (one from top)
Mechanical Motor timing: 28 degrees
FDR: 4.85
Duo 2 17.5.

with this it was coming off around 65 degrees C. It was as fast as a GM120 and SPX (there were no Tekins or SXX stock specs), but it wasnt any quicker. So I think I still need to find the sweet spot to get a little more top end out of the motor, as the punch was good but just needed a little more top end - and everything i tried (apart from changing FDR) seemed to just add heat.
