OK guys, i need some serious opinions on underdrive pullies. stedda of course. I have been going back and forth about getting them for a long time now. The only reason i have'nt is because of the cons that i have heard ex: dimming lights cooling issues. I drive the car everyday in the summer and i don't want it to heat up or my ac not blow very cold if i'm sitting in traffic on a hot summer day. Has anybody had any of these problems? And are the pullies really worth it? 


. The dyno results show gains from the pullies and the chip. Total 16hp improvement, and even more gains in torque. Even if you cut it equally, the pulley's netted me 8hp
