Hi guys, i have a 00' L, i just purchased a 01-04 ported Eaton which came with the 01-04 lower intake/ intercooler.. Now i know i can redrill the holes on the 01-04 Eaton and us it on my 99-00 lower intake (so i can use either my stock 99-00 lower intake or the 01-04)... I've read the 01-04 provide better mid-range power and the 99-00 better top-end power... Is this correct??? Which lower intake works best on our trucks???? Thanks
