Problems with FAST 90/90 I just installed the FAST 90mm setup on my 99 z28. Everything works except the air hose that connects the mass air sensor to the throttle body. Stock throttle body size is 75mm so I made a relief cut in the hose. When I slid it over the tb it ripped back even further, so for now i just put duct tape over the small air hole near the TB. Any suggestions on where and what i can use to fit the 90mm throttle body?

go to home depot and get some fernco hose.... 4'' to 3.5 hump hose
Well, I ran into the same problem. But, I had recently put a cold air intake on my 04 Z71. So, I cut the old bellows off and it fit perfect onto the the 90/90 set up. Just FYI incase you have something similar laying around.
Although, I did have the fernco mod, and it worked good as well, once you get it on.

You can fit the stock bellow (hose from MAF to TB) w/out cutting it. Intakehoses.com and hightempsilicone.com are some good places, as is Lowe's/Home Depot's plumbing section (fernco).
