I'm going to have the Stang reflashed. I have to have the speedo compensated because of a tire change and rear end gear change. While I'm at it I can have any other mods done. I will eliminate the top end limiter just because why not. But what other mods should I have done? Never did this before. Thanks

 

If you want to do a series of dynos, you could test several aftermarket options (expensive), better to wait for someone to test them and get a report, i.e., headers, intakes, etc. You could prolly go with underdrive pulleys right now if you're inclind to ever do so. Talk with your tuner and get their recommendations.
