whats the best throttle body off another car that would be a straight bolt on and at the same time give the most performance? and, or where can i get an aftermarket one for our tl because my 3.2 tl off the line is EXTREMLY slow because of my system and rims i have on there so i was wondering if anyone can help me out??
thanks

 

Well u can do what i did and sand urs down a little; it makes the car alittle faster and a lot faster throttle response..

 

ill def try that thanks. any recommendations on what gritt sand paper and how far down do you sand??
thanks

 

don't sand it down... just clean it with carb cleaner and polish it with metal polish. If you want more power, look into a type II intake manifold and get it port and polished. Then while you're working on that, bore out your throttle body to to a tapered design for a velocity stack style improvement.
