What would cause lower boost?

[FordGuy100]

My truck I guess is just throwing fits at me. So, my boost numbers are now down. I lost 1psi at 55mph from almost 2psi to maybe a little over 1 psi, on flat ground, no load. If I go WOT, takes way longer to make max boost. So, clogged fuel filter? Dirty air filter? Or more than that? It still boosts fine, just not as fast, and not as easily. Maybe I should get one of those intake gaskets to go on the intake hat for the time being.

FYI, I was gone in Mexico for a week, and havent had much time to get on anymore with the whole, trying to figure out what I'm going to do for the rest of my life thing breathing down my neck. Anything interesting happen in the last couple weeks I should know about?

I'm not loosing anymore coolant as well, those of you who read about my headgasket whoa's. I lost about an inch in the radiator, but no more?

boost or exhaust leak... or any of the things you mentioned

eliminate one at a time

Has the weather warmed up all the sudden? warm air is less dense than cool air,warm air =less potential for boost
Drastic changes in humidity can effect it as well,

That is most likely a leak as stated above, now the less likely options are fuel related unless Your LP or IP are on going south as well.

the mostlikely culperate for that is as stated a leak. check all the fittings on the impellar side or intake side of the turbo. the last on i worked on kept blowing off.i had to rough up the pipe to get the connector to stay together. make sure the pipe is Extremely clean. if thats your problem of course lol

I would check the tightness on the intake and exhaust manifold bolts.

also very well could be a fuel issue, has the smoke out the tail changed in color or volume?

It seems like there is less smoke which makes me think fuel, but I might be imagining thigns
