Re: Superchips, HEMI, wow.
Just remove the pcv valve and shake it; if it rattles is is fine, and a waste of money to buy a new one. Clean it and make sure to install it with the hole facing forward.
Cleaning the TB and installing a catch can to keep it clean, made a big difference in drivability and mpg with mine. Plugs made virtually no difference at all when I installed them at the 30k mark. EGR at dealer is $120, and at any parts store is $39 for a new one. I logged 45 miles yesterday combined HWY and city was 22.5 with the hemi, with just an AFE II CAI and no tuner.
