Rawze.com: Rawze's ISX Technical Discussion and more

On the information I got with my truck when I bought it it has a box that has my engine serial number and a portion that says 4.5 degree wedge what is this referring to and does it have any effect on my tuning? If you need any more information I'll scan the paperwork when I get home later today and post it up

dont wedge it at 4.5, wedge it at 4. If you want more timing do it with Programming, not mechanically at the engine.

So it's timing wedge well the way it's set on the engine I guess is 4.5 I didn't have a part in that the engine was rebuilt before I bought it
