Hey Guys I need some help.
07 Dodge Ram 3500 6.7 4x4
I just did a complete delete of the emissions and installed turbo back pipe delete and installed the smarty jr program.
Here is my concern as I accelerate everything is great until I hit 2000 rpms then there is a high pitched whistle as soon as I drop below 2000 rpms it goes away, if the exhaust break is applied and the motor reves above 2000 rpm it dose the same.
I went through and tightened everything I could possibly tighten that involved the air intake and turbo connections.
Is this normal or do I have a problem and if so what do I need to do to fix this issue.
Thanks for your help
