Tuners For 2018 Sierra "Hybrid" Truck?

Old thread but in case anyone is following, BBP has tuned at least 1 eAssist Sierra. So if anyone is interested, BBP can tune you.

I am looking for CAI ! And do you guys recommend BBP tune or a range?

Any CAIs will work. You just have to either make a bracket to rotate/move the coolant overflow reservoir, relocate the reservoir, or custom the intake pipe so that they don't obstruct with one another. 

 

If you just want to turn off the V4 mode and auto start/stop, then the range is all you need. If you want anything beyond that then a tune is best. I only know of BBP that has tuned eAssists. It's not supported by the others.
