when you say boost, do you mean forced induction or nitrous? if you get a retune, then they will definitely be able to work your shift points. possibly a one-two chirp if you go aggressive enough. but if youre going with serious horsepower like a supercharger, turbo, or nitrous, you really wont have to worry about your stock tranny holding it seeing as it is good to around 500whp. and i dont think youre getting there too soon. but if you do cross that threshold, look up freddy brown transmissions in long island. they make some serious stuff there. also, if i were you, i would upgrade the transmission cooler on the car ASAP. fords have a tendency to fry transmissions if you get a little too aggressive with them. i have owned seven fords prior to my current one. every one of them fried the transmission between 50 and 80k. i had one work van that would blow the tranny every 35k until i upgraded the cooler and never had another issue.
