does a UDP have any bad affects on anything else in the car(air cond., other accessories...)?

Power steering still works fine. A/C works in chicago heat and humidity. And I have a voltmeter, and at idle, and idleing for a while I've never seen the voltsa drop below 12, which is enough to start to start the car. Under acceleration and normal engine speed alternator is stil cranking out 14 volts.

i've had it for a while now.. it hasn't given me any problems. i had squealing on my power steering.. all it took as tightening the steering belt and it was fine.

when i first got it i noticed the improvement right away..

this a great mod to get especially while you are getting your timing belt changed.
