So, my buddy and I took it out this morning.. finally! To my pleasant surprise the truck ran really strong and it smoked LESS. Which is awesome, more fuel to burn and less to waste. I think because the guy had a 0 in it before and then he put the 5 in, and he didn't tune the afc (when he put the 5 in) and left it hot so when I took it completely out, it was a great pair up. Anyways, here's a video. I'm so flippin happy. I gained so much more low end power and a pretty decent difference in high end as well.
