Hey guys, Just wanting to know how much under drive pulley really help? And will I have to change my thermostat if I put a set on? Oh yeah, thought that I would share this with ya’ll just got back from Oregon and with all the stuff that I have on my truck I got an steady 18mpg driving there and the same on the drive back even though I was hauling and extra five hundred pounds in the back. Probably would have been better if I didn’t have to drive though the Mountains.

10-12rwhp... Nope no thermo change needed.
