I've tried a few tuners on my truck. Pro Comp Power Pro, Bully Dog triple dog and the latest a PPE standard xcelerator. they all did good except the bully dog was kinda sketchy. No problems yet but I know I need a tranny upgrade but my pockets are kinda shallow right now. My Question is the Transgo Allison Jr shift kit is affordable for me rightaway is it worth it , will it help or will I still thrash my transmission
