Nope. I'm in the process. You need the intake manifold off a TBSS or an 07+ 4.8/5.3 for it to work. I am doing the TBSS manifold/rails/injectors to get the 87 mm Sent from my Samsung Galaxy S4 using Tapatalk 4

What Jenna said. A lot of money and works best with a cam upgrade from what I was told.

I would only recommend going with a larger than OEM throttle body, if you have an FI application (even then, should be a 100mm+ TB). Otherwise, you will see no gains.

The 75 mm is good that high? I am still trying to find better than 317 heads to run with a GT2-3 cam

Your MAF and your engine will be the limiting factors. I have seen ported/polished TBs that make absolutely no difference. Just throwing money at a part that won't give you much as far as gains, if any.
