10 days in on the FP Tune with K&N drop in, Gibson axle back, and 91 octane. Self installed in less than an hour after a little issue with the anti virus program on my laptop (nothing to do with the tune). My startup routine every time, Start button, release the parking brake, spin the mode to SPORT. Throttle response noticeably improved, shifting much smoother though I do a lot of paddle downshifting in D (love the fact that it now downshifts on it's own), and I haven't really found that extra 30 hp yet as it's been raining for most of those 10 days.......
