I was looking to buy a 85mm Throttle Body for my 5.7 R/T. I was told by BBK that the 85mm would be better than the 90mm for me because I just have simply bolt ons (CAI, exhaust, 91 oct tune). However, I have a friend who has a 90mm TB that he is willing to sell me for a very low price. Should I just put that on? Will any problems occur, or will it be better? Thanks a lot for your input.

What year car do you have? if its a 2013+ then it will not work, Also the 90mm will not match up to your intake and you will also need a custom tune. IMO I would go either with a ported one or stick with the BBK 85mm
