So you think I’m only going to get 15 more WHP? It’s awd so should I expect 15 in the front and 15 in the back? Everyone thinks I will gain about 40-50whp but you think bc of the DME noticing airflow it will react and adjust so I’m not getting as much airflow as I could be? I want to get DP’s that let maximum air but just a little noise from exhaust and turbos. Basically sound stock until I step on it. I was planning on getting catalysts downpipes not catless. Your thoughts??

Thanks!
