So apparently the previous owner of my truck tried to do a port and polish on the throttle body. Not sure why, but its all scarred up. I never noticed it, but the dealership saw it at last oil change. I know they come with a special coating on the tb to help airflow and keep gunk from building up on the butterfly valve. Anyways so im on the market for a new tb. I found some pretty good deals on a BBK and a professional products tb. First question, is an 85mm tb too big? Only current mods are CAI and flowmaster muffler. I can get the bbk 85mm for about 269, and the Professional products 85mm for about 245. Should i save the 25 and go with a cheaper brand? or is bbk really worth the price? or should i save about 50 and go with an 80mm? any inupt is appreciated. Especially anyone that has installed one of these 2.
