So then what is it. Cause for some reason everyone at map thinks it could in no possible way be there turbo. But you want me to keep spending money trying this and that. How about you pay to have it remove and shipped back to you and increase wastegate or whatever. You ask me to try things and I do. Doesnt help and now this turbo is costing me more then my entire build.

That is pretty much what im doing now. Considering the boost controller cant control it anyway. Like i have said trying everything nothing working and just money flying out my pocket.

This is all part of troubleshooting. Unfortunately in your situation, you've had to pay someone to do the work on your car which sucks but you pay to play. Regardless of whose turbo (FP, MAP etc) it is, you will still end up paying the labor to R&R the parts. I've had to do quite a few turbo swaps on my own car within a year time frame (stock 8 to 20G to FP black JB to EF4) and it's definitely not fun (esp if you break bolts) but it's all part of the game. Heck, the EF4 had to be sent back to MAP due to lag issues (which got addressed) but here's what it comes down to. EVERY single time I've had issues, MAP guys jump right on it with good customer service and ATTITUDE. But you can't expect them to wave a magic wand and tell you what the issue is when their part has been installed by someone else and especially when they are lacking diagnostic data (data logs, boost plots etc). Believe me, I feel your pain. But give these guys a chance. They have yet to disappoint me.

18psi is not a measurement of preload. Preload is how far the actuator arm is adjusted, if you have the car pop the wastegate actuator arm off the flapper. Hold the flapper shut completely and take a picture of the actuator arm next to the flapper (while holding it shut)

For reference, here is the PM that was sent to seanr8368 on May 12th:

There is a slight chance that something could have happened to the housing during use, but unfortunately the only way to determine that would be to remove the turbocharger for inspection.
If I was you the next step I would take would be to try a new o2 eliminator downpipe. While the downpipe is being installed the technician can do a visual inspection of the wastegate outlet and ensure there is no obstruction.
In my opinion the chances of this boost creep issue being turbo related are very slim. I wish the car was here so that we could do the troubleshooting for you, but that's obviously not an option. I will say this, if we ultimately determine that the turbo is somehow at fault here, I will so everything in my power to compensate you for this inconvenience.
