Is this a good mod for a near stock 4.6L Stock 99+ GT?

Is there a big difference between the 70mm and 75mm?
flipnsac said:If you look on the link to the modulardepot site you will see that they did an initial test using an Accufab 70mm TB. Then, they did a "Part II" test using an Accufab 75mm TB. The Accufab TB/plenum out-performed others in both tests. The 70mm TB resulted in 264.61 RWHP and the 75mmTB resulted in 272.38 RWHP. That's why I went for the 75mm.

So truthfully better gains were found with the 70mm NOT the 75mm.
Dark Knight GT said:Ok. This data looks a little "suspcious". Ive never seen anyone gain that kind of hp and torque numbers by just switching to a larger throttle body. What is your source of this data ?
I personally run the stock 65mm throttle body and stock upper intake. I just ported and polished both of them and called it a day. Personally, I dont see where your going to net that much power by just going to a larger throttle body.
