Default C300 2016 w205 jb4 , limp mode underboost CODE - 09-21-2021, 08:26 AM

I finally got my jb4 installed , when I select any map I get a undeboost error code , any ideas I only got the tmap plugged in, on the guide it says the manifold pressure sensor is optional , any ideas? Is it the other sensor coming out from the jb4 or a possible boost leak?

Limp mode tends to happen when shifting gears, unsure if i should have the manifold censor plugged in, but the guide said it was optional.
