Heres the link to the how to. Its for a 65mm mustang throttle body swap but it also has the info in it for optimizing. Only difference is when you do the svt throttle body you will only crank the spring 1 time instead of 2 times like the mustang tb. The guy that wrote the how to is in the process of making a how to for the svt but its simple enough you should be able to figure it out. Any questions feel free to ask i just did mine a few weeks ago so its fresh on my mind.
