87 Performance tune vs Diablo tow tune

Post by davezirkle »

I have a 2014 GMC Sierra 1500 5.3 4x4 truck and a Predator 2 Platinum 7271 App Ver 13, IAP Ver 23, VID Ver 14, DB Ver 807, SN 201398372. My first question, Do all the canned tunes have the same trans settings or do they vary from tune to tune? I have been using the 87 performance tune and option the trans to Diablo value for shift points, torque and a 2 percent throttle boost and I like this setting. I going to be towing a 33 foot 7000lb travel trailer and intend to use this setting with 87 octane for the flatter lands. For use in the mountains I was told I could just add 93 octane to this tune and it would be essentially the same as the Diablo tow tune. Is that true or do I need to reset to the Diablo tow tune?

TCM tunes are the same regardless of pcm tune.
The diablo tune with 93 will add the max torque that can be safely added which is what you want for towing ;)

Thank you guys, I will definitely give the Diablo Tow tune a try. I just asked because one of the service techs at Diablo had told me I could get equal performance towing by using 93 octane with the 87 octane performance tune.
