The MAF sensors are VERY sensitive to airflow tumble effects. In short, if those intakes are moving around and or you relocated the MAF sensors, the MAF misreads will cost you power.

Also, the filters are not heat shielded, and that too is likely to cost you power.

Check out my proven power dyno thread (search my username and that); the K&N filters actually add quite a bit of power, and those plus smooth tubes are within striking distance of the G3's at half the cost.

Attempting to rate the impact of tuning mods with the butt dyno is ill advised -- if you compare that to stock + K&N on a dyno, odds are very good you will see big loss in power up top.

It will SOUND mean, and FEEL like its pulling harder, but its 50-50 at best that it's performing any better.
