Oh and boost psi is low on the gauge most of the time so it is possible that I have further turbo issues or a leak. This is the case either tuned or not.

 

Sounds like a mechanical issue. Either loose hose clamp leading to big boost leak or a vacuum line not hooked up correctly.

 

Yes could be. I just got it back from the shop a few days ago, it ran fine on the way home but i noticed not much boost on the gauge but no error code. I tuned it then drove it 15 min each way and on the way back it threw the code. I don’t think they resolved the issue. To add a new layer. I detuned it to take it back tomorrow and the light is gone but the boost still looks low. If I gun it I get around 11 psi but I think it should be higher and even some in between readings as well.

 

Do you have a way to datalog? Easy to check what boost it's running and what the target boost is in the logs.

 

I have never done it before, how do I do it? I have a launch x431.

 

Going a bit off memory. In diagnostics, read data stream, DME system, boost control system, and one of the parameters should be boost pre throttle plate. I typically record six parameters at a time, but you can do as few or as many as you want. Hit the record button. After you're done, remember to hit stop and save it.

To review the log, I recall you go under Profiles and it's saved there somewhere.

Unrelated, but I love using the Launch x431 to check the oil level. Read data stream, under oil pressure system or something, oil level sensor.

 

Thank you, I will give that a try

 

Took it back to the shop and they found a leak and the turbo may also be replaced. When I get it back I can give more details.

 

Yeah, with a boost leak, the turbo was likely spun too fast to try to make up the boost.
