I just finished installing the X02 racing FMIC on my '90 T2 (stock turbo, HKS intake and hks bov) everything is done and the car is running but i have a few issues. The idle is around 2200rpms and was around 700 before. The boost gauge shows over coming vacuum then i hit the fuel cut. I think i have a vacuum issue. Idk what to do with the 2 vacuum lines that went to the stock top mount, Should i cap them off or what. Also on the passenger side of the engine the big hose that went from the engine to where the intake comes out of the turbo idk if that should be capped or i need to run that to the new piping. im pretty sure these 3 lines are where my problem is ill try to get pics up so you guys can see exactly what im talking about.

 

put some pictures up. did you get the fmic on ebay?

 

x02racing is a vendor here on the club. Those are "ebay-like", Greddy replica.

Got the FMIC on my FD, running great.

 

pressure test for vacuum/boost leaks

 

Ok the one hose I'm referring to is the iac there's a big hose that went to the plastic tube under the inlet hose of the oem cooler, I cape it off and I'm pretty sure thats way wrong. I'll get pics up in a few minutes
