High Exhaust Temps. Not Alot of Boost

Ok, I am running a 2001 Ford f250 7.3. I chipped it and put exhaust on it about a year ago, maybe a little more. I noticed though that I have been getting high exhaust temps. So I had a mechanic look at it and they found a boost leak and fixed it. It still gets to 1400 degrees no problem when I lay my foot into it and this is without towing anything. The chip I have is an Edge juice with attitude. Don't flame me for it haha. I cant remember what boost is for a stock truck, but even with this chip, it doesnt get above 23 pounds. And to me, thats not very much. So I decided to put a K and N intake package on it. Just the basic one. My buddy said that he has ran those on his truck for years and never once had a problem. So I gave it a shot. Not much more power and still high exhaust temps. Does anyone have any idea what could solve this? Or atleast point me in a direction to look? I appreciate it.

Get rid of the K&N filter and get another cone filter cuz that thing will trash your engine.. and im sure someonee will chime in. that doesnt sound good.

As far as your high egt's there is a couple things it could be. May not be sucking enough air, may still have a leak somewhere or it may just be the tuner.

23 pounds is about what a stock truck will run.

When you say high egt's how high are we talking?

I think it's weird how the 7.3 has such a low boost when comparing it to a 6.0. I've gotten up to 35 pounds of boost on my 6.0. Oh and for your problem I'm not really sure.

if its just the truck, nothing attached to it, i can easily push it up to 1450 no problem prob more. and its not like it slowly gets there, you floor it and as soon as she boosts, its up there, so i have to back off. and when im towing i use the 2nd to lowest setting which is meant for towing and i still get high temps so i end up using the stock setting. it sucks cuz i could use some more power to tow, you know?

My bet is an exhaust leak around your up-pipe donut gaskets

Well for one thing get rid of the K and N if you value your engine. They don't filter very well and you dust your motor and turbo. Edge is also not the best tuning

A stock truck will usually hit about 15 pounds of boost.

I will look for another filter. I dont really know why I got the edge programmer to begin with. I think it was mainly because it gives you gauges as well. I know alot of people have had success with edge just like any other programmer or chip so i dont know why it would give me extremely high temps on my truck.
