I was in the suburban with the family fully loaded getting onto the interstate and I gave it a bunch of throttle. Around the end of getting up to speed it did some weird stuff. I see PE kick in and wideband is tracking, then in the middle it went back to stoich, then kicked in again. I swear I heard a backfire in there somewhere also, not a pinging noise. You'll see me punch it at the 12:22:16 minute mark. Tune and log attached. Thanks!
P.S. (Wideband is post drivers cat. 6.2l .005 over with Summit Forged 12cc dish pistons stock heads (upgraded springs) 9.5:1 CR estimated TSP Honey Badger Cam 218/230 .600/.600 115+3 LSA)
