This is a video from IDPs website. It seems as though the truck is studdering or missing at wot? My truck does the same exact thing with the extreme race tune. I was wondering if it was because its not getting enough fuel? I ran it like that a few times but it seems as if once it gets to that point it loses power?

I have ran some other tunes and it doesnt behave like that. I had been on IDPS website looking at some stuff and stumbled across this. I posted the video because mine does the exact same thing. I was wondering if I just needed to get it tweaked a little? Thanks

Stop guessing and get a fuel psi gauge installed. In that video, he let off the throttle real fast and caused a "turbo fart". It's caused by boost psi has nowhere else to go except back thru the turbo.

I'm not talking about the turbo fart I'm talking about the change in engine tone before that it sounds like it breaks up. I did just install a fuel pressure gauge this weekend. I hadn't yet run the extreme race yet. Just had not had a chance yet

The noise Im reffering to starts at about .09 seconds in the clip. It may very well not be anything bad at all. I just now running my tune the truck makes the same exact noise. Having never heard it before it kinda freaked me out
