OK sorry its so late of a reply but we figured it out the pre filters on these trucks has a check valve in it ( for some reason) this particular mopar filter had the check valve too far down in the filter "core" ( when the filter is properly installed a push rod touches the filter body and holds open the check valve) this caused the truck to starve for fuel ( not to mention the air leak at the front filter) i have no clue how this guy made it to work but it explains why we couldn't get a prime afterwards! Thank yall for your help

Got a good chance to verify timing this is after an hour at 70-75mph. Unfortunately I think yall were 100% right on the the effect ram air would have. Filter off on high idle right on 300 degrees EGT leaf blower feeding it i saw some dips down to 298 but pretty steady 300 still. Out of curiosity I took my hand over the intake till I saw a change about 2/3 covering egt started to rise till about 305. Morale of the story how easy the turbo breaths makes a slight difference. But it really don't make much difference. Not worth cutting the hood up.

It does have an aftermarket lift pump on it and uses a relay. Good idea on checking that. Tractorman I know your an 02 not an 01 but any way you can tell me what order your map sensor wires go? Should be an orange Grey red and blue black wire.
