Help reviewing logs?

Interested in trying to gauge health of turbos and whether I have a small boost leak. Just replaced all vacuum lines, plugs, and coils. A few of the vacuum lines had dry rotted at only 56K miles.

Car seems to be running well, but want to double check. Mods in signature, I need an FMIC still...

No, no downpipes. Makes enough power for street use IMO to not hassle with emissions, but I'd get an FMIC down the road. I know it'd help to have downpipes too though. Anyways, logs look good for a "tune only" car?

There are some corrections esp cyl 2. May talk to tuner about. Cant see your lpfp pressures. I like to see time from 3k to 6k rpm. You do about 5.2s, not bad could have expected better for your boost.
