After egr delete I only have 10lbs of boost?

I did the egr delete , afe filter and now I only get 10-12lbs of boost.? Did i hit a wire to control boost or what? The boots look good, put the sct programs and the the idp extreme x tune also, and still 10-12 lbs of boost. I have the stock exhaust on it now (the 5" is in the box still). Any suggestion??

Only thing i can think of is you didnt get the plugs seated correctly. the lower one maybe....i dont know. its been a while since i did mine. may just check over you IC boots anyway. sometimes they will just get loose, wear ......you should be able to hear the air leaking by even over your engine if its bad enough you only get 10lbs...
Guess you dont have guages to see your pyro temps? see if they are real high

Stock exhaust with dpf on? Are you running only a egr delete tune

I have the egr deleted and I am useing the tuner with the dpf and the egr deleted tune. It's not throwing any codes now, it just doesn't make any power or or any more than the 10lbs of boost

Would the exhaust back pressure sensor stop the turbo from building boost. The shop I got the tune from said it was because I have the dpf filter on it still. I read another thread and it talked about the the back pressure tube getting clogged up and of the sensor. Then showing too much back pressure so the turbo doesn't make as much boost

I had the same thing happen to me after i did my egr delete. You probably cracked the up pipe at the flex joint. Thats exactly what happened to mine and come to find out thats what happened. Now that does sound bad BUT there is a damn good write up on here and if i can find it again i will paste the link in here on a good fix that helped me out. Basically you can remove that up-pipe now and place the block off plate and the top where you unbolt the pipe. You will have to re-route the EBP though in order to do that. I can send you a picture of how i did mine if you want and we can talk. I fought with this for damn near 3 days before i finally found the small little crack. feel free to call/text anytime 8438707226 Josh.

I may be reading this wrong but are you still using your dpf? If you are that's your problem. If not then most likely your up pipe
