Sorry to see ya getting out of the Edge mode there. I usually leave mine set on the mileage setting as I do see a slight improvement in mgp's. Only once in a great while do I roll it up to the race or extreme setting for a quick romp. I never really push it that hard to think of breaking something internally.

 

If I was running your transmission I wouldnt be too concerned either. I never went above level 3, level 5 must be pretty fun!

 

level 5 is sweet until my tranny falls out..the it sucks! haha
