finally installed my bbk underdrive pulleys. Despite all the controversy no change in air conditioning cooling, alternator output even with a mild upgraded audio system even at idle with head and fog lights on, and no change in power steering, but i did gain 1.6 mpg on the highway and a little more in the city. and as far as hp, throttle response is definitely noticeable.

yeah and what year do you have? where did you get the pulleys from? how much they cost?...info...info...info...info
I bought them off amazon for about $150. Took about 2 hours to complete but having the right tools makes all the difference. Impact gun, fan remover tool and harmonic balancer remover tool. The fan and remover tool I rented from advanced which is free after you return them.

Same here love the under drive but I also added an electric drive motor that drives my water pump to save a few extra horses. For 90 bucks from summit racing u can get the water pump electric drive setup and easy to put on as well
