I've just purchased a supercharged NSX. It was tuned with test pipes with AEM V2. But the car is too loud for me and I want to put in the stock cats. Would I need to do a re-tune after putting the stock cats back in? Would I need to re-tune after putting in high flow cats in? I'm just worried it might run lean.
