Well I got my new tune from Nelson today and the truck drives alot better under 3500rpms but as soon as i gas it a lil the tach and speedo start to jump, my gear selector light jumps to reverse, and all power is lost. Also it threw P0449 code..
Possibly bad sensor in the motor?? Im stumped on this one

Install the previous tune, does it do it? Check for bent pins on the pcm.

yes it did it with the previos tune also, i just assumed this tune would fix it.. Could that code cause all the other problems? it literally drives 100% better at lower RPMs just does it when i romp on it..

How's the 6.0L running Chad?
~ Forged engine of some type ~ Ball bearing turbo of an unconfirmed size ~ 4L8000 trans ~ Beefy fuel system ~
Judging from his FB status, I'd say his Rhino is running better
