EGTs too high

[Morty]

I have an '02 F250 with an afe stage 2 intake, mbrp 4" turbo back, and TW 6 pos chip. it seems like my exhaust temps go higher than they should on eco mode, I have the probe in the manifold and it just seems like the temps get up around 1200 really quick. In the eco mode if i get on it i have to back out of it before I am at freeway speeds, and yesterday going up the the grade of the grapevine on the 5 freeway I had to turn off my cruise control within a few seconds. With no load at 73 MPH going up a 6% grade the EGTs were about to go past 1250. Does anybody else with a TW chip get high EGTs in eco mode, is there something I can do to make them not raise so quickly?

i highly doubt its the chip... you have a leak somewhere... start checking your up pipes and all your boots for a leak... what boost are you seeing when the EGT's are this high?

[Morty]

going up the grade yesterday the boost was around 12-15 but when I get on it to merge onto a freeway in eco, boost goes up to about 23

that seems pretty low... i could easily hit over 30psi with my 2003 7.3L with TW chip... you def have a leak somewhere.... check your up pipes for a leak... if your up pipes look clean then check your boots...

ok i will check because the highest boost i can get is 24 or 25

yah thats a lil low.. my 350 work truck with no chip can hit 23psi with just intake and exhaust...

[Morty]

yeah i looked at the pipes going to and from the intercooler, and I couldn't see any obvious leaks, they were pretty clean and the connections were all tight, is that what you were talking about?

[Raul@Stealth Automotive]

the up pipes are the pipes going to the back of the turbo.... if you look from under the truck for black soot around the back of the turbo where they connect it means they are leaking.... and you wont be able to see a leek on the intercooler pipes... that you will have to pressurize the system and check for leaks that way....

something to keep in mind, just because the truck is holding 1200 or 1250*, doesnt mean its gonna go higher. The truck can hold those temps all day long and nothing will happen. Next time check and see if you can get the temps to go higher (as opposed to letting off like you did I assume)
