What kind of vacuum numbers are you getting at idle? I'm trying to find out if I'm chasing a vacuum leak or chasing my tail. I'm only getting 6-8 inches and an extremely lean idle.

If you have an 88 without a mass air conversion you can't be running such a healthy cam. Thats your problem if no mass air is present

Unless he has a Ca. spec car ![[Big Grin]](biggrin.gif)
If not..you need some type of metering (MAF) to handle that kind of cam...

The car is converted to Mass Air. It has a 76mm C&L with 30lb injectors. If you guys are getting 15 inches at idle, then most likely I have a leak.
