Did a pulley swap last night on the HD. We removed a #6 and slipped in an 8 pounder! That is one big mother of a pulley. Took a couple of my buds for a spin after, not a huge difference, just more of the same. Lots of blower noise now too. My poor rear tires are going to take a s**t kicking
One of my buds had not been in the truck since it was stock-he was big time impressed. I am picking up a 160 thermostat today for instal this weekend. Guess I will have to change my signature soon. Maybe tonight I will hook up the vericom and see what I have gained by going from 6 to 8. Potential boost should be up 3lbs. Will keep you posted.
