About a month ago I put a PE COMP and guages on my truck and it hauled Butt. And now it seems to have lost a step or two. I cant prove that its not as fast but it feels like it. When I put it on I could make it smoke on level 5/1 and now it wont smoke at all. I am still getting 35+ in boost and around 1300 ET at WOT. But still seems to be a little less powerful than before.
