HI

I tried looking at the datalog to see if there was a boost leak. But honestly, am not experienced in reading the logs. I am hoping someone here can take a look and let me know if it looks like i have a leak somewhere. The highest I ever read on the dash was 8psi, but then again am not that agressive. But i feel like it should be posting more. Any help is appreciated.

I'm fairly new too, however with some quick studying there's a Boost Pressure Command metric (BP CMD) and I believe (take with a grain of salt) this is a measurement of how much boost the ecu is "asking for" to achieve the torque value requested by the throttle.

If you look at that, you're never really commanding anything over 8psi. You hit about 40% pedal travel tops, and in my opinion after driving for a while, that's not a lot of boost. You gotta really open that shit up to command ~24psi.

tl;dr:
Doesn't matter how much up in the RPM's you are, if you aren't on the throttle hard, you're essentially still just low boost until you tell the car to give you more with a little ~foot action~. Once you're past 3500 RPM, flat foot will give you full boost, "half foot" will not give you much.

You're barely even getting on the throttle. Even if there was a boost leak it'd be hard to tell at such low throttle input, but fuel trims look normal so I doubt it.

You don't have a boost leak. I mean you barely were giving it throttle. You were hitting your boost targets but your targets were very low. With the throttle at 25-35% your aren't going to be seeing high boost numbers.

In other words, say you were got near WOT and commanding 20 psi, but were only seeing 8 psi, that's likely a leak. But if you are commanding 6 psi and seeing 6 psi, that's not. You're just driving a bit like grandma. :cool:

While I'm here in the R section, if any of you haven't added your car to my community tuning reliabilty thread, it would be great if you did. Thanks.
