Hi everyone, I have a n54 on a MHD stage 2+ OTS map and I am going slightly over my boost target for a little bit then tapering off quickly. I understand that the stock turbos are supposed to taper off at higher RPM but this seems too much and at too low of an RPM. I have attached a log in 3rd gear from 3000-7000. My boost solenoids are brand new, and I have replaced the vacuum lines going to the solenoids but the ones to the turbos I haven't. They look to be in pretty good shape but I will try to replace them tomorrow, I will also do a boost leak test tomorrow. I do have way more mods than necessary for an OTS map, including 2" inlets and outlets as well as all other required mods. I am at around 5500ft elevation but I don't know if that's really my issue, i suppose it could.

I dont know why its falling off, but the inlets will cause issues on an OTS map. itll overboost from them. Mine also overboosted with inlets before i got a custom tune. You can see your throttle is closing when it goes over target.

This has nothing to do w inlets. Good looking log and turbos are giving it all...considering the elevation etc. One thing that may help is if wgdc is increased w a custom tune, but dont think there is much left...need better turbos

How many miles are on your turbos? Do you have any wastegate rattle?

I'm sure your altitude is playing a role in the fall off of charge pressures.
