Re: Increased Expedition Performnce???
I have added to a 98 Navigator 4WD:
Custom 3 inch true dual exhaust, with flowmaster 40 series mufflers
Powerdyne 9 PSI blower
throttle body spacer
20 rims with 305/50/20 Goodyears
Crossdrilled slotted rotors
I am running in the 310 HP range, and have a little more computer tweaking to work through
