Does anyone have any experience with this cam?
Its pretty new right now. I dont think anybody has run the 540 or 590 yet on a dyno. Probably call S&S for a dyno sheet I am sure they have some.
Guy on Youtube channel "Blockhead" done one in a LRS
I just had the s&s 590 cam installed in my 128 softail. Tuned by JD'S cycle works Nazareth pa made 150hp 145tq bike runs great.

Can you post the dyno sheet?
I just called Dave the tuner and asked him to post the Dyno sheet. I don't know how to post the dyno graph.

Where did the power start coming in? I took a look at the video from Blockhead and it looks to be more of a right handed cam. Can you confirm this?
Yes it is more of a right handed cam. Power comes on strong 3000rpm but still pulls good off the bottom. Works very well in my softail. Previous cams were s&s 550 rs552 and wood 9f60 .this is my favorite cam so far.

Were you making close to the same power with the other cams or does the 590 stand out by far in that category?
The s&s 550 135.84 hp 147.95 tq the rs552 139.04hp 142.28tq the wood 9f60 143.36hp 133.26 tq.
Forgot s&s 590 150.61hp 145.30 same dyno same tuner.
Did you by chance measure CCP after the cam install?
No previous was 230.

What pipe & comp you running ?
D&D fat cat 11.4 compression.
It would be awesome to see those 4 graphs combined to see their different curves!
Wish I knew how to post the dyno sheets. I'm not computer savvy.
Results matter and this cam when paired with matching large displacement, the right compression etc, seems to be doing fine. The timing is interesting and different enough between cylinders to change the CCP estimate to greater than 10lbs less on the rear cylinder. I know why they are doing this but just wonder how the driving impression is, normal riding and at slow speeds and how hard it is to tune.
Slow speed riding is excellent. Dave at JD'S cycle works tuned the bike and never mentioned any difficulties with the tuning.
