Upon startup the motor is a bit choppy since it has no maf. Within 10 or seconds it idles perfect. Ofcourse there is a low speed torque loss off idle, but this is only when tooling around in stop and go traffic, which I do not do very much since I use other vehicles. All other areas the car runs fine, and there are no drivability issues. I am quite happy with it. I do not know how these cams run with a flash, since I'm running a standalone. To me my 
tells the story. If you are daily driving to and from work long distances with stop & go traffic, I would probably use a slightly smaller stick- 272-or 264 depending on the situation.

I would think there is probably at least 20 HP there. The 280s are going to move more air so spoolup should also improve slightly. With the EMS you should have no problem getting a good idle and a great tune to boot. There are stock turbo cars running around with 280s and EMS that idle just fine.

noticed that you were from colorado and wisconsin. if you are in colorado contact mac autosports they have plenty of dyno results for different sized cams for the evo. they say up here with the 264 to the 272 there was no power increase between the two. they have more info in it then i do , here's their number, 303-841-1176.talk to bill. good luck.

Idle quality depends heavily on both the tuning and the cam settings.
I am right at the 400whp zone (Dynojet speak), and this is with 93 octane + methanol.

Ted, I have read elsewhere that the intake cam on the HKS280 has a lift of 10.2 (vs. the 264 and 272 cams which have 10.8).
Is this accurate? Does this likely contribute to the ease of idle?

In order...
Hemibaby: I am absolutely satisfied with the Nisei IC. IMO, it's the most efficient design for an EVO IC I've seen. I obtained it directly from Nisei at the introductory price. The performance numbers I'm getting with meth are very much on par with numbers typical of C16. Max boost press is 25psi.
ez76: The lifts of all the HKS cam sets are identical. Likewise, more aggressive HKS grinds are made in equally stepped increments. For example, I already know that if HKS releases another EVO cam grind, it would be an HKS 288, with 230 deg @1mm and the same 10.8/10.2mm lift.
ph2280509: The cam gear settings are +2/0. This is a very aggressive setting that is intended to give a big midrange torque punch at the expense of a few peak hp. It works.
