TLDR: Best time has improved to 12.3@115. Previous best was 12.7@112 with BF goodrich sport comp 2 summers. New Michelin PSS helped as well as the tune. Absolutely recommend!
So it's been about 6 months and I wanted to follow up on this same thread. My F is an 08, 94k miles, stock headers with cats intact. Wheels are slightly lighter Gram Lights 57CR with 285/30 Michelin PSS in back, 255/35 P4S in front. I have the Borla catback with mufflers off, Joez intake elbow, with AFE dry air filter. RR Racing tune has been great thus far with zero issues. MPG has been the same, I can feel a nicer torque difference around town driving and especially on the highway. On both sheets below I am on the left. Sadly only got 2 runs in. Times were with removed spare and KCLV at 23.8. First run PSI at 36, second(best run) at 32.
