can someone give me some insight into why my car is adding so much fuel @5300 - 5600 rpm ?
also why my maf reading goes from 24lb/min to 34lb/min in the same area ?

Post a tune file and some more info about the car.
I posted a log file , it is a coyote swapped foxbody with a 2018 intake . Stock maf transfer stock OP VCT. Not sure posting the tune file will shed any more light then the log file will.
here is the tune file

Did you unhook the IMRC, rewire, or use a plug and play kit?
What are the mods on the car, year engine, intake manifold?

What intake tube are you running. You say factory. Is it the 17 or the 18? And are you using the maf housing for that tube?
Factory 17 tube and maf housing
your MAF curve is out. Not sure why
I think I'd try cleaning it before I made any tune changes. The MAF curve in your posted tune is correct for a 17 intake tube and maf housing.
I just noticed 6000+ RPM and 0 MPH.
You need to drive the car.
I wouldn't trust any WOT blips.
OK sorry, it does look like it is fully warmed up.
Hopefully someone with more knowlage than me will chime in.
Yea, I caught that also. Hopefully cleaning the MAF sensor will fix it. I hate spending money on a guess, but I would try a new sensor if cleaning didn't work.
Good luck and I'm subscribed for the fix.
