Hey guys, i just got my AF/X pulley today.. and i was reading the instructions... first thing they say... "The AF/X Pulley is not intended for highway use on any pollution-controlled motor vehicle"

As always, i'm paranoid... so what exactly does this mean? To the people who already have the UDP installed... has it affected your daily drivability?

they have to put that on there for their liability.. its just a disclamer and from all the peeps on here that have udp's there have been very little if any probs with them and reliability. i still have mine sitting in my box... :-( it will get on there eventually.

YES. it has affected my daily drivability by making me go that much faster!!!!
Seriously, its just legal mumbo jumbo the makers put on there in case some kid wraps his car around a pole and his parents want to sue because that is the obvious reason why the car was fast enough to wrap around a pole!!!!! Don't sweat it... its all good! Install and enjoy. just watch out for the UPD police...
