Other threads I read suggest the only way other than having the rollers in the front move off the back rollers, is to have a tune. The threads I read through were saying even in the SRT pulling those fuses didnt do much but increase the limit from 4500 to 5800. He could try pulling the wire that hits the huge fuse in the engine bay, I dont remember what thread it was or what it was called but it did the same thing as pulling 17 and 18 but for '04's. I could take a pic if need be? It disables TC, ESP, and ABS
