my mods are:
GAIC 4bar
4bar FPR
N75J
Forge 007
GHL CAI
APR DP w/ custom 2.5" exaust
The reason I ask is because I believe I'm running a lil rich. with normal driving, my gas mileage has dropped. no vag-com so I don't have any logs. Any suggestions?

Good idea to go one range colder with a chip.

I'm installing Autolite 3922's today (1 heat range cooler). It's a cross-reference to the NGK BKR7E.

Why? What possible reason is there to go colder? APR recommends using the factory specified plugs in a chipped car.

every 50 or so hp increase you should go heat range colder is what the rule of thumb usually is.

Depends. Water landing or hard surface? How high?

The "50hp rule of thumb" is nonsense. Who came up with that? Explain to me WHY you need to go colder just for clarity sake. I'm just trying to get some some answers based upon FACT, not gossip or "rules of thumb".
