I say to lock the current rules for 3 yrs minimum.
As for turbos, all the shops that make turbos are always gonna say this years charger makes ** more HP than last years. That's how they sell more parts and stay in business. Sometimes they do find a little more and sometimes they don't. It's up to each puller's budget to upgrade or not. One thing for sure is to take every claim with a grain of salt.
