Gotta work on my 0-60 now cause I'm roasting the 285's with the nanny's turned off at launch. manual trans. I haven't dyno'd the car but I've gotta be up about 40-50hp in total. 380ish crank I'm hoping.just over 300whp maybe. still haven't tried E85 yet though I've got the tune for it already. That & exhaust are the only NA options left on the table at this point. Wanting to go Overkill stage 2 next year I hope!

That sounds awesome! I just ordered my k&n CAI since I caught it for cheap on Amazon. Will get the JacFab later this month it's looking like.
