2003 6.0 upgrade help!!

Hey everybody, I just bought a 2003 6.0. I have heard all of the horror stories about this motor and was wondering what I could actually modify without screwing up the motor. It has the egr delete done but will putting an aftermarket exhaust, cold air intake, or programmer mess up anything with this motor? Thank you for your help.

I know that modifying any motor to extremes will mess up any motor if you hot dog it. But I am just talking about a low power programmer, aftermarket exhaust and cold air intake. Many people have told me that any of that stuff at all will mess these 6.0s up because their so touchy. Is this true?

Last year we put on a SCT Livewire and have no head studs and have never had a problem for the last 25,000 miles. Knock on wood.

Get either gauges, or a monitor like edge cs or sct livewire will also monitor many things. I prefer the looks of analog gauges myself but many people use the digital monitors for ease of install and their more parameters they are able to monitor. Keep an eye on egt, oil temp, water temp, fuel pressure.

Coolant filter and engine coolant flush to an elc coolant is a great idea. Most will tell ya to stay with stock air filter assembly unless your way moded. Its a great set up and will work up to 500hp.
do some serious reading on here and searching and you will learn more than you can imagine!

if you really want a tuner definitly go sct with custom tunes. You can run some great tunes without studs if you arnt stupid and keep an eye on the vital temps. Most good tuners will have a tow tune available that will get ya 50ish hp and still be able to tow max capabilities, but I wouldn't do it without gauges.

Paintingman Why no pulling trailers? I pull a 27' traveltrailer 6000# and my construction trailer 10,000# + and no grief. I think the issue is pulling blind meaning if you dont have instrumentation to monitor and adjust your driving to your load capacity you will have problems. Too many folks buy a truck, mod the hell out of it without realizing that you have to monitor your engine, trans and diffs. You cannot just chip your truck and drive it as normal with a load and through mountain passes. But that shouldnt mean you cannot chip your truck and pull a trailer you just have to be aware and listen to her. These trucks are the ****, i wouldnt have anything else but my 03 6.0
