I'm creeping up on 100k on my truck and am planning on doing a full tune up when the weather perks up a bit. I figured that since I'm planning on tossing a new serp belt, I might go ahead an toss a UDP on. Has anyone had any long term negative effects? Love it? Hate it? The alt pulley will get swapped out as well.

Honestly there in no point in even doing that, I wouldn't waste your money.
