Well judging from your post you do have ssrx dlc. So my advice would be to keep making adjustments until you find the ones that improve your time. Rember to only make one adjustment at a time so that you can isolate the effects of that particular adjustment. I also recommend trying to use auto while tuning that way you get very precise consistent times. I usually do my suspension 1st and once I have that dialed in move on to my transmission. It seems tedious but it will yield the best results. I have upwards of 3 hours in some of my tunes.
Also, welcome to gtp! 👍
