2019 Titan XD Pro4x Cummins
That has to do with the way the tunes are for most deletes. I still get turbine whine but it’s significantly less. Interestingly though, the turbos do a lot to reduce the exhaust sound pressure level, so with more of the turbine exposed, there is less whine and more note.No it won’t hurt the performance enough to matter. Yes, it will quiet down the whistle a lot. That the main thing with these trucks, it’s the turbo, it’s so damn loud lol
Either case, spl does go up after a delete.
