Hey just recently completed a turbo swap on my 07 lsj. Everything looks right and for some reason it idles super high like 3k. Throttle body only goes on one way, stock lsj throttle body/intake mani on zzp adapter plate. Revs if you give throttle. No check engine lights. Anyone have any issues with this

 

vacuum leak

 

Can it be in the tune? I've got the top vac port going to the bov. And the compressor has a port I sealed and connected to the bottom of the wastegate. Connected brake booster hose to adapter plate. Still need to cap off breather port Idk what else it could be.

 

try posting in the turbo lsj section

 

^^^this and I agree sounds like a vacum leak probably before or after the tb.

 

its going to be a vacuum leak, check you throttle body gasket, along with the adapter plate gasket. make sure you dont have a spare vacuum port you havent capped.

 

Okay thanks I'll check. I have posted on the swap thread and don't usually get responses
