Terrible uphill performance in my 6.0

[jerseydrummer@yahoo.com]

Help..... I have a '03 F-250 4x4 6.0 with an auto tranny. These are the mods...4.5 inch Donahoe Racing lift kit. 35" Toyo Open Country A/T's, K&N PIFK, Silverline 4" After Cat Dual Exhaust, Superchips Flashpaq tuner. The truck runs great. The only problem I have is going up steep hills. I can't go more than 55 to 60 without the EGT climbing to it's limit (1200f). I'm not pulling a trailer or anything. I live in NW AZ and the elevation changes from 500 to 6000 feet above sea level. I have the tuner set to economy which is the mid level performance setting. Can anyone tell me what's going on?? Thanks

Try an SCT with custom tunes. I have heard most of the others can run hot.

I doubt an xcal2/3 with custom tunes will help your issue. Is there anymore info you can provide? Is there smoke? what color? What, if any, past issues have there been? Is there a cel? good luck and welcome to the org.

take out the cat and the muffler

can you go faster than 60mph if you wanted or are you saying the truck won't allow you to go faster then 60mph up a steep hill? If you can go faster than 60mph then I agree completely agree with the other two posters, lose the cat and muffler and get an sct.

Go turbo back with the exhaust, dump the cat.

actually i dont see the problem at all.
i have a 6" lift and 35's and going up hills on the hiway will get over 1200* in a hurry. there is no problem, this is normal.

and for the record, 1200 is NO PROBLEM for the 6.0 i run mine on the hiways in AZ all the time at 1400 and have done NO damage to my motor (and yes i've torn it apart and checked ) these motors are extremely tolerant to EGT dont be afraid of 1200, you can run your motor at 1400 for hours on end with no damage.

and believe me the power you can make at 1400 is quite noticeably more than 1200

i hope this helps.

and even a very mild tune will make over 1200 easily.

Thanks everyone for the replies. I really appreciate it.

if it will ease your mind i will take you for a ride and you can watch my 1500* pyro maxed out on the peg for as long as you like, these engines are INCREDIBLY egt tolerant.
