wow! thats all i can say. when i got the truck two weeks ago i thought it ran good. now that they put two injectors and a egr valve in this thing rips. now i know how these things are supposed to run. i'm blown away. even seems like my mileage improved some too. the dealer took care of me too by waiving my $100 deductible and hooking me up with a loner car. didn't even have to ask for them both. right now i'm smiling ear to ear. think i'll wash the monster on this 60 degree january day in pa.
