question and about H&S and deletes

[outlawed250]

hello,

I recently installed a 5" flo pro straight pipe, s&b intake, H&S MM and block off plates on '14 platinum f250.

after the install I notice the idle is a constant deep rumble. I have noticed on many other deleted 6.7s that while idling the motor will cycle through 2 to 3 different exhaust notes/whistles. I am wondering which is normal, and if I may have missed something along the way? the truck has 30k miles and I unplugged both orange connectors for the butterfly valve and egr.

I'd say your good. Mine is sounds different every day...

turbo vane checks? They become much more audible after exhaust

You're fine and have nothing to worry about. My old HSP tuning was the same way for the most part.

thank you for the quick response! is there a tuning related issue that could prevent the vane sweep? the trucks seems to run fine so I don't believe the vanes are sticking. the only thing I have noticed is the ebp never really goes above 4-7psi

Your vane sweep is keeping the vanes from sticking... That's the point.
