I agree, your boost and boost target are way off.

You also seem to be pulling some timing, fuel?

log it...3 gear minimum -- 4th gear preferred; 2,5K to 5,5-6 will do...then post link to log...

Well I think I may know what the issue was, I turned off DTC but not DSC... I dont know how I missed that, lack of sleep. But I am hoping that was the issue, I will do another test run tonight and see if I get a better log.

I really appreciate y'all looking at my datalog.

^ that discrepancy shouldn't make that much difference...don't go off 2/3 gear, seat of pants...you have awesome logging abilities off a little android device...lots of channels and great resolution...logs are a very good means of troubleshooting and fine tuning, custom/etune maps etc...

Red face

New runs just now with DSC OFF. I also re-flashed Stage 2

Maybe this looks better?

Absolutely. You have a boost leak, almost no question about that. WGDC is maxing out, and it's off by even more PSI now... I've run with DSC on and boost and boost target should still be close to each other.

PS, mind if I use your logs as an example on my blog?

Yes you can use them for the blogs. Glad to be an example of a boost leak Ha-ha

Thanks for your input, I am taking it up to the shop tomorrow and they are going to do a smoke test. They are just weirded out because I am not throwing codes...

I thought the MHD ethanol OTS map was for e20? Would help explain why the rail pressure is dropping so much if you are running around e35

Turn on "gear" in the log. You will see that the fuel rail dip correlates with the shift from 4th to 5th then again from 5th to 6th. I'm not sure if that means anything but there seems to be a correlation.

Wait wut? Everything says E20...the app, the site, the posts. Even Martial himself said running beyond E20 isn't good.
