dfuser boost tube only 21psi

so I just put on a Dfuser boost tube and it didnt make any difference i still only get 21psi. So thinking the boost tube just didnt work I completely took the hose off from the wastegage and still I only get 21psi. And yes all the connections are good, and No the comp isnt de fueling itself. any ideas?

I do believe that the boost tube doesn't create more boost. It just delays the opening of the waste gate. More fuel = more boost as turbo etc.

the connections from the turbo to the intercooler are good I mean theres some oily stuff on the connections but there still good and the connections to the Y pipe are good. Where else could it leak? But I know the boost tube doesnt add boost but you would think with all my mods I have it would have enough fuel to create more boost. I mean I'm not complaining the truck is plenty fast but I was just wondering if you guys thought my turbo was on its way out?

you need to start with a better wastegate . banks big head holds more than the oem i know youve got the hose off your oem wastegate but that doesnt make it hold more boost it just stops it from opening on comand but it will still only hold so much before it blows open and if its weak 21 may be all it can hold

Oh I see, that would make sence. The only thing is it seems like you have to buy panks whole system to get there wastegage. I cant find there bighead wastegage anywhere.
