2015 Silverado 5.3 Intune I-1000 Torque Management Question?

[BillyB087]

Hi, I just recently purchased my new 2015 Silverado with the 5.3 engine, it only has 600 miles on it and I purchased the Diablosport Intune I-1000 and installed the 87 Octane tune with the torque management, DOD/AFM and speed limit disabled. Also bumped the throttle boost up to 20%. Im wondering about the torque management. Was that for the engine or the transmission? And will it cause any long term affects if I leave it off? I see some people say to leave it on so I was just wondering, don't want to mess up my brand new truck lol. And also would I see any more of a performance increase if I use the firm shift tune or maybe use 89 octane gas?

Also what tune and settings do you recommend for best performance?

the tm setting was for the tcm, up to you if you like it on or off....best performance comes from the diablo tune and use with premium fuel.

Thanks
