12.5 is a good A/F ratio for the RL, most cars make peak power between 13:1 and 11:1.... I'm making 260 right now with 13:1 at redline. I have 60lbers going in soon though. That little 'hiccup' at the end is sorta odd though... He's running 12:1 or fatter for 95% of that dyno.
Pulley down soldier! I'm dropping the 2.6" on next week or so, HP Tuners will be here Monday.... good bye torque management... I'm expecting 300+ whp with tuning, new injectors, and the smaller pulley again. Should be around 250 tq, maybe higher with the tq management turned off.
