Hey guys I'm ordering eurocharged tune and pulley ..will tuning my 55 in this state fail smog/emissions test ?any 55 owners here in cali have that issue or we are good ?

Tune and pulley will not adversely affect emissions. I passed with pulley, tune and throttlebody no problem.. Headers are where you run into issues. They wont pass visual, and if you remove cats, the emissions will fail sniff test.

pulley and tune pass just fine
