Wasted $600 on a fancy air intake that did nothing

I bought a cold air intake for my 2015 Mustang GT because a buddy swore it added 20 horsepower. After install it actually ran worse and threw a check engine light. Took it to a local shop in Austin and the mechanic said the stock box was already pulling cold air. Dyno proved it made zero gain at all. Anyone else get burned by a mod that seemed legit but was totally pointless?

That dyno probably measured airflow at the intake vs the stock curve and the stock one actually flowed better.

Change the filter and see if those numbers flip.
