OK...i just bought a trick flow upper intake plenum. now i want a throttle body to go with it. on the trick flow website is has a chart with the CFM ratings of the different components together such as , the stock plenum with a stock TB, then with 70MM , then a 75MM. then they have the trick flow plenum with all 3 TB's and the 70MM has more CFM than the 75MM! does this make sense to anyone? if so tell me why. i need to know wheather to buy a 70MM or 75MM.
heres the link to the chart so u can see what I mean
