    I port matched the 75mm from the 65mm intake opening, took me a little while to get the whistling to stop with the throttle body, grinding the iac ports etc, ended up adding a 1/8th hole like the 65mm frpp one and it worked great. Had to drive it a day until i had my buddies volt meter to set the tps, after I set it, she runs with a little more pep now, actually WAY more pep :nice:

    Well the iac holes in the throttle body supposedly the culprit, but i massaged them pretty good and it still did it, then i added the hole.

    The 65mm frpp had the hole in the left side but i put mine on the middle right to disrupt the air flow around the iac ports.

    Many may not like this approach but i feel i did it safely. I stuff the intake with a towel, placed the 75mm gasket on, drew with a pencil around the edges, took the gasket off and used a dremel to port match the edge and went a little inside the intake. Then used a vaccum with a tube piece, then pulled the towel out, used vaccum a little more, then a light damp towel rub, a little more vaccum and then reinstalled it. I could massage the inner a touch more if i get bored and want a project, it was real easy.
