Boost loss

I think I have a boost leak on my f250. I have the H&S Blackmaxx and on the Hot Damn tune lately I'm peaking boost at 33-35lbs. When I first got my blackmaxx I would see numbers like 47lbs and even once 50lbs.

Are there any specific areas I should look for the leak at? Or could it be something entirely else thats causing the issues. I already redownloaded the tune and put it on the blackmaxx.

I would start by checking the silicone boots connecting your intercooler lines. Used to be a common problem on the 6.0/7.3's. Ive even seen intercooler's split on the end caps disconnecting the tubes themselves. Hope this helps.

This subject brings up a good question.....how much pressure can the stock CAC take before breaking? I don't think I have seen any posts regarding the actual CAC breaking, just the boots splitting or slipping off.

the boots are what you'll have to worry about, I don't think you'd really have to worry about splitting the pipe

Ok so I checked everything out and I have 3 leaks.

1) Cold side off the intercooler out to the motor and was pretty small...fixed
2) Cold side into the intercooler off of the turbo and looked to be massive....Fixed...I hope
3) Cold side of the small turbo and I have no idea how to fix it
