Too much turbo lag?
I was just wonderig how long it usually takes for the turbo to spool up?
It seems like mine is taking to long, and according to my gauge I only build about 18psi max, I used to build about 22psi.
Anyone know what could be causing this?
I cleaned my turbo this weekend, I know the up pipe is sealed around the turbo perfectly, but could my up pipe be cracked somewhere?
Or would something else cause lack of boost?

I would suspect something is leaking post turbo on the clean air side, maybe a leak around one of your CAC boots or MAP hose.
I had a leak in my stock up pipe in the section of flex pipe and did not lose any boost, just had an annoying tick going on.

Your up pipe is probally got a crack in it . I am pretty sure mine does, i had a bad leak at turbo but fixed it but still have leak somewhere. I think i had the leak before i tore it apart cause i could smell fumes in truck a little while heat was going while sitting. You know i allmost pulled y pipe while waiting for oil cooler but didnt, thought leak was at manifold and up pipe guess it wasnt. I am not pulling turbo now will just deal with it for the hollidays, pull the pos in january

Well with the turbo plugged in I get a hiss, when I unplugg the turbo I get a nice deep rumble.
I know this hiss was never there until I did the EGR delete, is it possible when I pulled the turbo the pipe ended up cracking?

Some flashes have a vein sweep programmed in that you can hear exhaust tone change with the position of the veins.
What EGR delete did you go with? Do you still have the stock up pipe or did the kit have a piece of straight pipe to replace it?

I believe he means that he welded a plug into the end of the up pipe that supplies exhaust gas to the EGR cooler. It would leave the stock appearence of having an EGR system, but would eliminate exhaust gas from flowing through the system. It is a cost effective way to eliminate the EGR system. When doing this you also have to cut the scoop that directs the exhaust gas to the EGR system out of the stock up pipe.

YUP!!
This does a better job than only having the egr valve closed and exhaust getting to the cooler, My truck was like that for a while, then I finaly put the time into working on it. The heat of the exhaust does not get to the coolant(egr cooler) as much, even though it is still attached to the up-pipe.
