Either you have a boost leak, or the wastegate arm was not set correctly. It's kind of strange you almost hit boost target and then it falls off and can't maintain anything close to target

n55david · 11-05-2022, 08:03 PM

Can you post the actual link to the log and that that datazip stuff please?

Hello Friend

I checked multiple times for boost leak. I am 99 percent sure that there is no boost leak now. How do we check for that wastegate thing?
Your response will be highly appreciated.

i have added some more logs in my topic too.

Btw i dont have any codes before and after few pulls. Can it be still the wastegate issue?

Its a process using the scan tool. If you installed this yourself, and didnt use a scan tool to install the wastegate actuator, then that is almost def your problem.

Huge boost leak

thejeremyman9 · 11-06-2022, 01:33 PM

Yeah its almost certainly a boost leak, not only because of the boost below target, but because the STFTs are pulling 25% fuel. So you are almost definitely leaking air after the MAF

Could it be because of oem turbo inlet?

No.. 100% not. You have a leak between the turbo and the throttle body. Likely at the intercooler and charge pipe or at the charge pipe coupler.

However the oem inlet is hurting your power capability.. but that's has nothing to do with your boost leak.

Pressure test from turbo inlet forward with 25psi and find the leak

Zinia · 11-06-2022, 11:23 PM

You already got all the advice you need. There is a boost leak - you're at 100% WGDC because your turbo is trying to meet target.

Get it to a shop or start checking the Chargepipe and IC connections yourself.

More than that turbo will do safely and reliably over time.. about 22 to 24 max. If you have the proper supporting mods.

Just to expand a little, you need proper hardware mods (i.e., fueling) AND sufficient fuel quality and software/tuning.
