3.3TT Low boost. Help me.

[minkyu1008]

Hello.I don't have a Stinger, but I own a Genesis G70 3.3 RWD.I installed JB4 a month ago, but I think there's an issue with the boost.I came here to gather information and have a question.In map 0, the boost is around 10-11 psi, and both map 1 and map 2 are not different from map 0.The final boost in map 1 and map 2 is 12 psi.
According to the tuner, it's a problem with the car's turbo, but the manufacturer's repair shop says the turbo is fine.
Is there anyone experiencing the same issue?
Thank you in advance for your response.

11-12 psi is normal for stock -- it's not an exact psi but a load that the ECU charges, so it'll vary a little.

On map 2 you're ending up in the same place, but not because the ECU is calling for 11-12 psi -- it's calling for 6-7 and the JB4 is adding the 4-5 that it normally would for map 2.

I'm not sure if this is what logs look like with overboost/limp (I thought the JB4 would detect those but maybe not), so maybe that's what's happening. If you don't get a better answer here try the jb4tech forums.
