Any Ideas?? Tricky problem!!

I have been a member but I am rarely on here since I sold my old powerstroke. You should see me on here more often now. I bought a 2001 F250 from a friend of mine. The truck has some history and has a long story behind it. I will start with the stats on the truck. It has almost new everything or everything has been replaced. New motor with about 10k miles on it. FPR shimmed Adrenaline hpop, Edge evolution, Up pipes replaced with motor rebuild, 6637 intake with riffraff cover, 4" turbo back exhaust, CCV mod, Tank has been removed and cleaned and intank mod done, Computer has been swapped, New Map, New IPR, New ICP, New FUel Filter, Used turbo put on at motor swap, Ebpv works perfectly.

The truck dynoed at 303 hp and 667 tq in Denver at the fund raiser dyno event. Here is the problem or my concern atleast. The truck has never seen over 20lbs of boost. Not pulling a 9000k lb boat, not with the original motor never. Not even with Stage two injectors in place at one time. I have high egts 1500-1600 wot. I am open for any suggestions or advice. I know the first comment is to get rid of the edge. The truck runs perfect no issues or concerns. This has been an issue for over a year.

I will update my profile and sig right now. Thanks Again

how close is the sensor for your pyro to an actual exhaust port and how far into the exhaust manifold is it? is it touching the exhaust manifolds walls? also first chance you get ditch the edge.....

The pyro is in the exhaust port per the instructions. As far as touching a wall im not positive on that. I am working on getting a custom tune but I need to figure out the boost issue first hopefully.

Have you tried a boost leak detector? How are the up pipes?

Honestly sounds like the tune or an inaccurate boost gauge. Truck doesnt need to go over 20 psi to make great power. Why worry about it?

It does sound like you may have a bad pyro gauge. Cuz with egts that high your internals wouldn't be happy.

The Edge is all electronic guages. I have done a leak detector but I plan trying it again tomorrow. The up pipes are factory but the gaskets have been recently replaced with small block chevy donuts. I realize I dont need high boost numbers to make good power but. I run 19 lbs of bosst loaded or unloaded plus I run 40" tires. I would think with the load on the motor and for whats done I would see atleast 25lbs. I know I am kinda stuck on this and ideas will slowly stop coming because I believe I have tried Everything lol. I am hoping someone can either relate or think outside the box. Has Anyone seen different numbers from a mechanical guage vs electronic? More accurate? Significantly different readings?

I tend not to trust electrical readings. That may just be a dumb idea but i like to know what the actual reading is.

I dont know how the tuners work but it might be blocking the map sig after a certian psi?? Just so the pcm doesnt freak out.

If you are wondering if things are workin right, try unhooking the wastegate and go for a drive but watch the boost gauge! I dont think it will get outa hand but you have quite a bit more than stock components.
