ATT: Anyone with GM Stage 3 Pulley + Wideband
Wondering what AFR's you guys are running after the pulley swap on the stage 2 tune, I've got the pulley ready to go on. Not that i'm scared, more or less curious, and i'm waiting till the weekend to put it on, thanks again!

Hey Scott,
I have been running a 2.8" for a while and when I got mine dyno's at JD Racing my AFR was good, I am however going to a 2.9" pulley to be safe with the injector duty cycle, much more info has come out on the 2.8" pulley and IDC since I purchased my pulley, i am planning on using the 2.9 as a daily use pulley and put the 2.8" on for some racing.
