Default ECUTEK + misfire CELs???

Hey gang,
Got an Ecutek reflash last week on an otherwise bone-stock 2005 wrx with 5500 miles. Actually, I do have a UC Berkeley license plate frame, which adds about 3hp.
A few days later (but NEVER before the reflash), I got a CEL that flashed and stayed on and was read as a misfire by a random service guy at the dealer who was cool enough to help me after-hours (I didn't tell him about the reflash). He said the ECU had logged only one misfire and not to worry about it.
Anyway, there have been two occasions now that I get a misfire CEL while gunning the car in 5th on the freeway. I haven't had the codes pulled yet, but the CEL blinks for about 4-5 sec then completely disappears. At no time during or after is there a discernible deterioration in performance. I called my cousin who is a ASE trained and AAA approved automotive electronic mechanic and said that it is unlikely (but not impossible) to be caused by the reflash and is more likely to be a hardware problem (coils, plugs, etc). I've scheduled a dealer appointment next week and another appointment with vishnu in about two weeks, but wanted to know what experience you guys have had, as i don't want to drive the car til then if it could potentially be bad. Is this a common problem with ECUTEKs on otherwise stock cars?
regards,
h
