I have a H&S Tuner and I'm DPF deleted with EGR disconnected. Also running an S&B CAI. Right after I installed this set up my turbo has more of a screech sound then a nice whistle while spooling up. Mostly between 5-15psi. That's with normal driving. Anyone else have a whistle that's closer to a screech noise? Its only on acceleration, performance has been great when I want it but the screech is annoying.
Power is nice, love the exhaust note and diesel smell. My mpg has gone up by 3 on the hiway. I don't flog my truck at all, I did this for better mileage and it is my work truck so it needs to be reliable.
The main reason I went with a tune to start with was because FORD in all their cheapness wouldn't replace my DEF pump that failed,,,not covered under my drivetrain warranty(bumper to bumper is expired). So I decided they weren't getting anymore of my money and I would just tune out that garbage.
I would be worried my turbo was about to fail if this screeching started weeks after the mods were done, but it was immediately after that it started. Since I own an early 2011 the turbos aren't great to begin with, maybe I should be looking for an aftermarket turbo soon to cure that noise.
