engine misfire?

Hi all,

First post in a long while. I have an 02 996 turbo with 23k miles. Mild mods consisting of ECU tune and exhaust, installed 2 years ago.
In the last few days I have noticed what sounds like the engine intermittently cutting out at full throttle. Sounds like very fast staccato, if that makes any sense, No idea whats going on, thought someone here might help diagnose this problem. Any thoughts before I take it in?
Also if anyone can recommend an independent shop in the LA area.

Thanks!

Henrik

Are you getting any CELS? What plugs are you running? When you added the mods to your car, did you change the plugs?

No CEL's. Stock plugs, didnt get replaced during upgrade as far as I know. Sounds like that might be the issue. So Denso plugs are better than stock?
Thanks guys!
