High EGT's and lack of top end power

[mxracer428]

03 6.0, ive been noticing that i am really lacking power up top. i stick it down and seems to just get louder, im running a max street tune also, i did have an injector replaced becasue a bad o-ring and that helped some, but it still feels like there is more power if i dont go full throttle more like 50-70%, like i said whne i go full it revs up with lack of power and very high EGT's. say in the 14-1500s. when i hardly ever saw them about 12-1200. tubo is good. thanks

VGT issues?

Boost leaks? Check the IC piping.

i want to say that this didnt start to happen till after i installed the banks Big mouth air horn, and there IC pipe. i could be just trying to point my finger at something but seems like the right time frame. had the horn off this weeknd to make sure the gaskit was good. took it to work sunday and still goes right to 32psi and wont go any more. and you can just watch the EGT's climb. whats the thoughts?

you're making plenty of boost. I would check all of my intercooler boots. When you hammer it...the egt's are gonna continue to climb even though you are making boost, so it might not be anything to worry about.

Where is your pyrometer? pre or post turbo?

pre turbo, and it hits 32 very quick in the rr's but it wont climb with the rpms, seems like the truck just gets louder. as when people say check the boots what am i checking for? they are all tight, cant seem to find any holes, one is new and one is stock. (post cooler). my boss at the diesel shop insists its running out of fuel. but im %80 sure that it wasnt like this when i first got the tunes. it sure didnt climb to 1450 egt as fast as it does. thanks for all the help.
