Diablosport i3 worth it just to raise idle

[SNES Avalanche]

2011 5.3. I got the i3 with the main purpose to disable AFM and raise the idle. Raised the idle 100 RPM and now at idle it is super smooth, no more hiccups while sitting at a light. I am just using the 87 tune for now, may install the 'firm' transmission tune as well. but so far it is working exactly as I hoped. I also may play with the idle and see if +50RPM gives me the same smooth idle.

Took your advice and did the same thing.

It honestly feels like a brand new truck!
