Turbo whisling

I checked the exhaust and there is a leak in the front pipe, an aftermarket part that I bought against all advise. My bad. So will that produce lower turbo pressure's? The truck pulls like a bull on steroids up a hill but the pressures still won't go over 34 to 36 when I used to have to back off to prevent it from hitting 40 sometimes. It sounds good with the exhaust leaking, makes me want to put straight pipe on it. The stammering it had has stopped but I haven't pulled any in the mountains again yet. Finally getting home this weekend and since I have to have my 120 day inspection done I will be fixing the exhaust. I have changed the crank case breather filter on Saturday and it does need a service this weekend. I will try to check this post but since my dedicated run is gone now I have less time to get on here. Thanks for any and all help you all have given and will give.

After you get it solved, it sounds like you need to have the boost levels lowered a bit if it is really easy to get it to 40+.
