Another Raptor forum really liked
Goosetunes with a COBB tuner. I have zero mods and got a 93 octane "custom" tune. You email back and forth with the guy a few times and get a final tune. I have no dyno numbers but the seat of the pants experience is worth it. The COBB tuner also allows for other adjustments (turn off auto start/stop, remove the 107 mph limiter, adjust pedal fly-by-wire feel, etc.). I tuned it and keep the tuner in the glovebox, but you can keep it plugged in and monitor gauges and record all sorts of stuff if that excites you. I did not wait on the warranty. I added the tune at about 15k and currently 21k. My only complaint, I went through a set of tires in no time......
