Default how do you run logs like this (values per rpm)?

I ran a meaasure of block 2 on my own S4 (Stage 1 w/ Abt chip). I am experiencing sluggish/ low boost and thought it was a bad MAF. Unplugged the MAF and I'm still getting weak surging and it doesn't "feel" like it's reaching full boost. The passing power I had in 6th gear is not as smooth or as torquey as it once was.

The issue first came up on a trip to Big Bear, and seemed to be worse a altitude...not so bad at sea level, so I'm scratching my head wondering wtf.

I was seeing a peak of 265 g/s, so it can't be a bad maf right?

Yeah. Could be a boost leak though. Check the F-hose & TBB. Pressure test the intake.
