Anyone install this yet? What was difference over stock?

Also is it obvious that you have installed aftermarket pulleys? I mean obviously they will be a different size than the stock pulley, but other than that do they look stock. I know my dealer is stupid, but they arent that stupid if the pulley is a different color or the design is difference.

Anyone have any pics of fthe pulley system?

 

anyone?

 

I have them, but with the fan cover back on you can't even see them so I don't have a picture.

 

Are they worth the money?

 

i have mine and should have it installed tommorow.

 

Chemgod - so you got the tuner & underdrive pulleys... so the obvious question - how much 'peppier' is the truck? In theory you've just tacked on 40hp or so, correct?

 

How do you like it? Noticeable performance difference?

Also, will a halfwitted dealer be able to tell the difference when the truck is in for service?

 

Ive tried the pulley kit on my Mustang and the Cc never worked right and the lights would dim at night when I had the heat on. Has anyone had these problems with the ones for the F150.

 

dzervit,
I have had good luck so far. No dimming of the lights or anything, but then again I don't have a large aftermarket stereo or anything. It can break my 35's loose now . Anyway, It was well worth it for me.
