Yesterday I added 3.73's Steeda pulleys D&D motorsports uppers and lowers and tuned it with a Superchips microtuner. Wow the sotp feeling was a huge difference, I am loving the new gears it pulls much harder now. Before I put these mods on I dynoed 251/283, I am curious what I will do now. Does anyone have a guess also what times are possible with the mods in my sig, Im going to the track on Friday.
