Hi guys,

Here's a log of my car. I've slowly been fixing issues with it (incorrectly gapped plugs, leaking axle seal, the list goes on). Cobb OTS Stage 3

https://datazap.me/u/stevenma188/speed-3-3rd-gear-pull?log=2&data=3-14

Any idea why I'm only hitting 15PSI of boost? I have had it go higher before, but it seems to only want to boost that much right now. Does it look healthy-ish?

I would offer my opinion but the file will not open. Can you upload it to the forum directly? stevenma188

You can do this by clicking the "Go Advanced" in the post options and attaching/uploading the file.

My bad, did some cleaning up of the datazap.me account and the link went dead.

Working link now.

I have also attached the csv file to this post.

Have you cleaned for MAF sensor recently and have you check for boost leaks? Check your BPV for leaks or if its broken.
Your AFR are slightly rich but nothing is a red flag in your logs.

I have been dealing with my own tuning problems from boost leaks so I may be biased about hating them... I am trying not to be biased... but at this point all car issues are from a boost leak.

Keep us updated, I am happy to help but being on the other side of the country I can only do so much.

One thing I did notice is the car is always hard starting. Takes a really long time of cranking before it will start. Will definitely check the MAF and also start looking for boost leaks (I also suspect that).

I also intermittently get code P2188 (Fuel system too rich at idle).

If that doesn't work, clean your MAP sensor. They get gummed up bad in the intake manifold from our direct injection + EGR.

Use the MAF cleaning spray for both, if that wasn't obvious lol.
