High negative LTFT issue

Hello everyone, I am having an issue with Very high Negative LTFT issues recently on my 2007 Mazdaspeed 3 I have run a boost leak test already and I am all good there but my LTFT is at -18 to -20 when driving and around -16 when idle. I am only on my base map from Justin at freektune which I know will cause some Negative fuel trims but I compared my logs to my buddies logs on his base map and our idle LTFT is the exact same but when driving his are only around -9 so I do not believe my high off idle trims are tune related. a couple areas I'm suspicious of are my forge BPV because I got it used and I believe the spring in it is too heavy because the car flutters anytime I let off while in boost could that cause the negative fuel trims because the bypass valve is not opening to recirculate? only other area I am suspicious of is the MAF sensor in my car does not look correct to me it says Toyota Denso on it and I don't believe there is any way that could be correct for my car. just wanting to see if anyone has any ideas before I throw a bunch of money at parts trying to fix something that could possibly be a cheap and easy fix.

 

Post the logs here too.

 

I have never posted datalogs before so I’m sorry if this is a stupid question but do I just drag them straight from accessport manager to here?
