Has anyone here had the 2009 Forester "Reprogram ECM (engine control module) re catalytic converter on PZEV (California emissions cars) only" done? If so, has it affected the performance in any way?

I don't notice any lack in performance since the reflash. It seemed to just smooth things out. I can still launch cd cases outta the cubby from stoplights if I want :biggrin: 09-10 owners will understand lol
