No.. on my truck I have multiple controls just for certain things.. I have a water-methanol injecton system that I have to constantly monitor my boost, to turn the amount of methanol injected up..
I also have to watch my EGTs (exhaust gas temperature).. which goes along with the methanol injection to cool it down.
I also have to watch how high my trans temp gets, so I can manually turn on my transmission coolers.
I also then have to turn the power levels up and down on my performance chip to keep in line with each of those.
So one hand is always steering, and another hand is always on some sort of control.. not to mention I have to push my exhaust brake going down hills.. as well as look out who's around me with a 40-50ft goose neck trailer that I'm pulling.
As well as utilize my trailer brakes.
It's harder then you think
