s200 tune got erased??
Ok so i got my car partially tuned in april. shortly after that i had to pull the head and change the head gasket because my head studs backed out. car was sitting up until last week when i put it back together. i slap the head on on and go to start it and it barely idle's. A/f is around 11:1-12.8:1 at idle. also now it doesnt want to rev past 2k rpms. Prior to me pulling the head it idled around 15:1. could the tune have gotten erased?
