To the floor board.
I normally run my ts chip on the 140 setting but today i turned it back to stock and the thing was so slow!!! When i mean slow like it couldn't get out of its own way. it ran around 6 pounds of boost. What in the world would make my truck this sluggish? it has 126000 on it so it should be wore out. Please help!! also i have a mystery oil leak coming from the back of the motor and i dont know where its coming from. its a 99 so if anyone has had these problems feel free to tell me some solutions
