I see the same thing. My first response to this thread, post #2, asks if maybe these are dyno plots before the Gernby tune. Stock ap1vs stock ap2. Nothing here looks like a <4k rpm vtec.

 

The dyno image is from Chuck, not from OP

You can clearly see his F22C is tuned though, it doesn't have the big VTEC bump around 6k that stock tunes always have (like the F20C in the same image does)
His bumps a bit more around the 3600 he has his VTEC switch set at, but around 5000-5500 he is paying for that with a dip it seems

But he doesn't seem to be making much more power than what I'd expect a stock tune F22C to make

There's some weird things going on with his dyno plot anyways, WOT AFRs 14-17? That has to be incorrect or he is destroying his engine

 

Yes its Chuck, not OP, but Chuck said report is his Gernby tuned car, and a stock ap1 to compare to.

I can't read any of the numbers on the report. Its all just blur.

 

Greg (Gernby) tuned my 07 AP2 back in 2016, I had him touch up the tune to accommodate when the A/C is on. The idle was dipping and hesitating a bit. I can honestly say my car's been running great and the torque curve is much more linear than it was previously. This being said I've never had a before and after dyno to compare it. However, if there's interest and there's someone on here experienced with reading the datalogs I wouldn't mind having someone look over them just in case.
