I don't have the 2.5 RC kit, but I do have a 6" lift and BlueCruise. A lot of members have leveled their truck and BlueCruise still works. I had to have my cameras recalibrated. The added hight made the truck's cameras not mesh together in the 360 view and it caused the truck to always hug the passenger side of the road or parking stall. It would pretty much park you a few inches off the parking line or drive down the fog line. The recalibration did help with BlueCruise and parking. It's not perfect and still struggles time to time with rough roads and high winds. It makes it ping pong down the road. I believe this is because the truck thinks the steering input is for a small stock truck and tire, not a lifted truck with 37x13.50 tire on a wide offset wheel. I believe the truck tries to correct itself with a subtle nudge and it doesn't change course. So the truck gives it a little more and it ends up overcorrecting. On smooth roads with no wind its drives down the road just fine with the BlueCruise on. Most people that are leveling are running a 35" tire or smaller with a 9"/10" wheel in a +18/+20, I have seen a few 0's. I think that would only help compared to the -25's I have. I personally believe the trucks steering rack and electronics don't like the heavy tire and wheel combo with more resistance to turning, not the height of the truck.
