I tried to do some logs but when i went to look at it in excel, it wasnt showing anything.

 

Any ideas?

 

What turbo and downpipe? If the dp is divorced the wastegate might be hitting the lip inside keeping it from opening all the way. It happened to me with my atp3071 turbo and the grimmspeed dp

 

Did you try viewing the datalogs through the Cobb software, or just through MS Excel? IIRC, the file extension for datalogs is .csv and I can't remember if MS Excel reads that or not. Worst case is you download AccessTuner software, but I don't think you need to go that far unless you find out your wastegate duty cycles are low and need to raise them.

Keep me posted and I'll help as much as I can via PM.

Its the stock vf39 turbo with the bellmouth invidia downpipe. I'm tuned on open source. I've done logs in the past but Idk what happened this time Lol. Maybe I have to download the hex definitions instead of the standard? Its really weird that this is happening.

 

If that's all you have done to the car, it leads me to believe it's either a bcs (which you have already tried), a break in the wiring to the bcs, or your wastegate values (or even max/target boost values) are off. Without any logs to look at, I can't rule out map values as the culprit.

You can try un-installing/re-installing your open source software and look for definition updates. If you're using RomRaider, I would suggest downloading hex definitons.
