What's up PSA???? Long time reader, first post.. I do most of my posting on FTE but I tuned & deleted a month ago and PSA has the best info on Aftermarket so here I am!
So I am running a custom tune and when I get on the throttle around 1/2-3/4 I get a loud howling noise under the truck right before the truck shifts from 4-5. As soon as the shift completes the howl stops...I'm only running a 500hp street tune.
So, I called the guys who wrote the tune and they said it's fairly common and it has to do with the trans clutches and the overdrive gears. They said one of their race trucks does it every run. I don't ever remember hearing this before I tuned the truck. Everything I have read has usually been how solid the trans is..
So.... Does anyone have any experience with this loud howling noise???? Is it normal?? Is it a bad tune??
Thanks in advance!
