Although this is my first post, I'm very knowledgeable about how the forums work. (previous cars) I tried searching for this but I can't seem to find anything.
So I have a 98 GT Automatic. I noticed it starts to lose power at about 5500 and so on. The car doesn't shift until about 6200. Before I look into tuning the computer and so forth, I'm wondering if a 99-04 v8 TCU would work? Looks like it shifts at about 5800 and puts it back at 4000. Although it would be shifting early, this car feels like it has a shift kit already when it shifts since it goes from very little torque at 6000+ to loads of torque + peak horsepower at 4500. Whether it shifts into 2nd/3rd at 4000.. it will have a lot more power than it would winding out 2nd gear. 1st isn't that bad since it gets to the shift point pretty quickly, but 2nd is the killer.
