Another Accessport question

[AntonioZ]

Hey guys,

So i know you see these threads a lot with people having questions about accessport flashes and boost setting. Well, this last weekend i decided to install downpipes on the car, go stage 2 sport on the access port, power is awesome and the sound is intoxicating! I then wired my accessport and logged a couple pulls and found my peak boost was hitting in the low 20's and that the boost gauge on the access port wasn't reading any vacuum( No negative boost per say). I will try and upload the logs tomorrow and will probably head to Cobb Surgeline in the morning to see if they can figure it out. I did notice on the stage 1 before downpipes it did hit around 20 psi of boost on the accessport which seems old. Just thought it was interesting and wanted to see if someone else has had the same experiences, any suggestions, knows if its safe to run?!

Thanks!

I think the general consensus is that around 14 psi is the safe stock turbo limit since this is close
to what the same turbos are tuned to in the 1M. Pushing any part past its design limits
will shorten its life and I wouldn't recommend 20 psi if you want to be safe.

stock turbos can do much better than 14 psi safely with the right mods and fuel

That being said OP,
Please post logs your boost should not be exceeding 20 psi

Here are some logs, I wasn't sure how to upload them but I think that link should work. Let me know if not. I am not sure exactly what I'm looking at when i look at the logs so please excuse my ignorance on the matter lol.

I also have Chris at Cobb Surgeline looking at the logs to see what he thinks. They weren't sure but they were concerned about the high boost and why there is no negative vacuum/mercury (if that is the right term).

Thanks in advance for the help,

Just a random log. boost looked ok but i noticed i have no vacuum.
