My TB has gradually started shifting too late I think, maybe I am spoiled because my Mustang shifts perfectly. Can the dealer reprogram this to be like it was new?
At first I thought it was lacking power but cleaned the Throttle body and it still does not feel right.

04 with 65 grand on it.

If it's out of warranty, a PCM tune is the best mod to wake up the vehicle and make it perform BETTER than new. And it can fix the shifts, as long as nothing's in the middle of breaking.

Check the vendor section for PCMforless.com
