Ls7 hot restart goes lean
Want to see if this is normal or if any of you guys have seen this. I've got an 08 z06 fully built h/C/I. Cam is a btr stage 3. The car runs and drives very well as I've tuned it myself. Maf curve and VVE are all -2-4%. Whenever I shut the car off and restart it, as soon as closed loop turns on it pulls fuel until the wideband is showing 1.3 lambda or leaner. The engine changes pitch so it's definitely going lean. Does that for a few seconds then settles back down to 1. It's not really an issue just curious to find out why it does this
