I went today and did 2 runs. I knew my car was running rich; but thought i would have broke 200 hp. Stock ECU and no VAFC. I'm installing the AEM EMS in the next 2 weeks with the help of David & Daniel at R&D Motorsports. That should help. Here is my graph from the 2 runs.
3500 miles on the car. Oil change scheduled next week.
My mods are as follows:
Spoon Header
Mugen CAI
Spoon thermoswitch
Spoon thermostat
Spoon rad cap
B&B Triflow exhaust(dual)

No. I'm not running a VAFC. I will be installing the EMS soon.

WOW! That sucks...

Looks like VTEC never kicked in...

Your low RPM Torque is very nice though ~120 all the way down

hmmmm,

Did you dyno before the mods?

torque looks bad, but even though HP is just below 200, it isn't bad at all. interesting at 3500 miles that the vtec doesnt' seem that pronounced, which reassures my instincts and butt-dyno that the f20c doesn't start 'kicking' into vtec until 5K miles (in my experience).

might want to try (seriously) removing the exhaust and then re-dynoing the car. some cars have shown to regain power by reinstalling stock cat-back systems. this could be the issue.

Wait, so you used to have a VAFC and then took it off bads2k? How long before testing did you take it off? There could be something in that.

Here's my dyno...



Very easy to see VTEC engagement and torque below VTEC is similar to yours.
