Ok, finally got the 531 and IPD turbo cam installed on the 90 745T. Pulls around 10-11" of vacuum at idle, very unstable idle, sounds like it's laboring. The head has 37.5 exhaust valves and mild intake tract porting, fully rebuilt/checked, clearance at .013" cold. Also the car seems to have a rich bog til around 2800 when it wakes up and pulls like it should. The cam is currently running straight up since my cam gear is now a paperweight (hooray for first-gen IPD gear and 40k miles).
Anybody have any thoughts? I've already checked for vacuum leaks, car was running fine beforehand, no other work was done, timing marks all line up.
Thanks!
