Well I don't claim to be any expert on this by any means so if you could go into further detail on why you don't believe this I would like to hear it.
I would think since the primary and secondary lobes are both indeed different than stock that its not that hard to believe. And I just looked at real street graph and it looks very similar

After a little calling around, it looks stonesilverap2's results are pretty close to what is expected for these cams. I guess people are seeing really good results without tuning, and even better with! Huh...

Tempting, if these actually made ~10-15wtq and 10-20whp across the entire band without tuning, and I would be able to pop these in my car that currently tuned makes 140wtq and 220whp and make those gains, I would drop the money on them instantly. But 160wtq and 240whp on an ap1 seem a bit of a stretch

Like I said before, I would imagine that gains on an ap1 would be a few ponies less, like real street made 13 whp. But every engine is different so ya never know I guess.

i've got those.
my engine is F20C2 with all possible bolt on mods and a tune (vtec at ~5600)
could drove only ~20 miles but the car definitely felt punchier at 4-4.5k and up in high gears.
3rd gear is strong all around.
the top end felt somewhat rough. maybe becuase quite significant increase in engine noise.
looking at logs and Gernby's soft dyno the top end looks not smooth:
maybe after all keeping stock valve springs is not enough and valves float indeed....

The increase in engine noise may also explain the rough top end if the knock sensor is pulling timing.

springs are springs.
i suspect they're the same for ap1 and ap2.
retainers are diffrent.
my enginne is F20C2 and comes with ap2 retainers.
so retiners wise the updgrade is not a must.
my tuner came back to me taday and says that he don;t see knoks.
