Go run it, if it's a m6 you should have high 12s @ 110 or even a little better. Depends on your driving and elevation. My guess if you don't have experience you'll be in the low 13s after a few passes. I have seen full Bolton 5th gens run 14s because the guy has no idea what he is doing behind the wheel.

12.8s about right, you should be there too. Allot depends on air temp, elevation at the track that day. If your under 2000ft you should see high 12s then, if your in real good air like 500ft you could see 12.6 @ 110 With a auto I would foot brake the car to about 1500 rpm for the launch. Lower rear tire pressure to about 25-27 and do a good burnout. It won't take much to run low 12s with an auto, easy to drive

FWIW I run an underdrive pulley and didn't bump up my idle rpms, and I still charge at 12.7 at idle in traffic and see 13.8 on the highway.

What does your car run stock?
