My symptoms:
Car shakes a bit in gear @ idle;
Bogs a little bit every once in a while (dips below idle when coming to a stop);
Developed a slight ping @ 3/4 throttle...even with different brands of 93;
Slight power loss (cant confirm this, might be mental), but the car doesnt feel as strong.
I dont have access to a VAG, so please dont suggest to VAG it...lol.

My engine mods:
GIAC FX03
Genesis 386cc
Forge SPLT-R
Magnaflow exhaust
Four brand new "R" coil packs (one blew on me and replaced all four a couple of weeks ago)

I know there was a thread a while ago regarding GIAC PINGERS, so I know there's people out there with this issue as well.
AWE seems to think that the pinging is a non issue, suggesting to run the tank of gas out and try another manufacturer. They also say the GIAC recommends the factory plugs.
I think I'll change them out this weekend, but what's the best plug for the GIACFX tuning and living in the NorthEast?
Thanks in advance
