Ok, pulling the sled Wed. Placed 5 out of 14 last year, used level 2 of Edge w/ attitude.

Question is, will level 4 be toooo much and limp trans on a 300' track??
Will the trans make it to near the end before limping?
Would level 3 be a better choice, last year level 2 just traced a little smoke and ran out of power when truck up shifted to I think 4th gear.

Truck does not pull real hard, not a shard as pulling a 38' trailer in the mountains @ 23000#, probably because of low side transfer case and slipping tires on dirt, nothing slips on pavement.
