just got back from the drag strip after running 3 consecutive 13.6s. first was a 13.69 at 97mph, then 13.65 at 97, and a 13.66 at 98mph, was lauching about 2,100 rpms to 2,300 rpms. think i spun a front tire on the last run. this was a big jump from my old 13.9 runs.
When do you need to do these? im on my 3rd spin on filter in 31k miles, just wondering when you change the fluid and internal filter. I drive it hard, i pull trailers and fords often, and use my truck everyday. Thanks
