Ride quality seems ok. But something in the front suspension is making a squeaky noise when the truck is cold, and it goes away after 10-15 mins of driving. I'm suspecting the front shocks.
My 24 Raptor seems to have the same issue. I only hear and feel it when the truck is cold. After it warms up, the noise seems to go away. Truck has 24k miles.
The ko3s on my RR are fine. I rotate them every 6000-7000 miles with oil change.
the Ko2 that I put on my 4runner were hard to balance. The steering wheel shaked really bad at 60mph.
I have had mode shifted on me twice. Now that I think about it, both times I was driving on the same road, almost the same place. Maybe it is certain vibration (or potholes, etc) that is causing it to shift by itself?
I just installed the tune myself. I figure the FP warranty is only 36k miles, and I am already at 15k. It's probably not worth paying a dealer to do it.
First impression - definitely shifts better, and feels more snappy off the line.
