Howdy,
I am very near to tuning my 2016 3500 DRW Megacab 4x4 with an Aisen transmission. I am leaning strongly towards Double R Diesel Ray's emission tune. I am curious about how these non-tunable Aisen transmissions are acting in the real world with tunes up to the 100-120 level. I understand that after that level, they can get a bit confused and overwhelmed as they cannot be adjusted electronically (yet) to handle the added torque. Any feedback will be greatly appreciated.

Thanks in advance,
Randy / PAINTHOUSE
