With the off season coming for many of us the thought of engine builds begins. I am also contemplating my build and I am interested in hearing thoughts on who has tuned their tranny after their engine build(auto only of course). I realize not all mods depending on attained h.p. will not require a trans tune. But most mods are going to have an engine tune that may increase the redline. Just putting on headers will require a tune. With a redline increase shouldn't the shift point in the trans also be retuned? GM I am sure has a very conservative tune on the shift points and most cars would see an improvement even without an engine build. What do you say?
