I installed the ORA tune on my '19 two weeks ago. The only performance mod I have is a resonator delete. De-performance wise the truck is on heavy 2 pc wheels with 37" Nittos.
They tell you to drive "easy", no WOT, for about 250 miles. Well, that's effin hard to do, but I did my best, so for the first few drives I wasn't thrilled. Right around the 220+ mark I started treating it like I usually do, which is a foot in the ass often while driving. After several runs, I thought it ran really well. Hit it from a dead stop it accelerates and shifts right, hazes the tires through first, its fun. Cruising speed/passing zone acceleration is more fun now. Am I happy, yes. Do I still want more power, "did you really just ask that?" DUH
Flip side. For those of you coming from a tuned diesel truck, the tune will not feel even close to what performance difference a tuned diesel gives. I'm coming from a tuned and deleted LML Duramax and previously a tuned 6.0 Power Stroke. Remember diesel tunes can give you a few hundred lb ft of tq increase, so hell yeah your going to feel that a whole lot more than you feel in a tuned Raptor. That being said, every Raptor deserves to be tuned. I have nothing to compare it to, but I do recommend the ORA550 tune.
