Long story short. Just got tuned yesterday and installed the day before AMS wide mouth dp, TOMEI cbe, AEM intake at @#$% ^&*%$. Car was a blast and sounded great on the drive home. This morning I woke up and pop the hood to look for the grimmspeed ebc that I thought they had installed before the tune. No grimmspeed ebc. Instead I see a nice shiny purple tube shape gadget at the location of where the grimmspeed was suppose to be. Did some searching online and found out the purple gadget was a Hallman pro manual boost control. Oh forgot to mention before the research of the purple gadget I did turn the knob counter and clockwise a few times and lost track of original location not that I was keeping track. Called the shop and they said it was there miscommunication part in not updating me on the grimmspeed malfunctioning after 2 pulls on dyno. They replace wit Hallman for me since I was strapped on dyno already. Told them bout the knob turning they said to turn the knob low boost all the way than counter turn 2 revolutions and drive mildly until I can bring back to them to accurately adjust the boost. I have no boost gauge and definitely no knowledge of boost controlling or tuning. My question to you guys is since I altered the mbc setting. What does the shop need to do to get the settings back to the tuned 22 psi. Will I need to get on dyno again and retuned? Is it safe to drive before accurate boost adjustment? Also will like to know some feedback on numbers produce on parts installed and tune. Thanks EvoMr's

 

I have a hallman pro.there is a + and - arrows on the knob.all you have to do ...I would start by just turning the knob all the way to - and boost the car full throttle in 3 or 4th gear.look at what boost you are running.Start turning the knob to the + around 1/4 turn at a time.Usually around1/4 of a turn is around 1PSI of boost.good luck.ohh and once you start to get close to your desired boost level I would start to turn it like 1/8 a turn or less just to be safe...You do not want to boost any more then you were tuned for.

 

how will I look at what boost I'm running? I have no boost gauge as mentioned.

 

Ohhh well then you are SOL...I would just turn it down all the way to be safe.That will be WG pressure.Get yourself a boost gauge!
