I had my truck in for a mode selector issue. When I got it back they said they took care of the recall. It’s a CA emissions issue so I was worried about affecting performance. I don’t live in CA so it kinda pissed me off. The factory cold air intake is CA approved. I don’t understand what exactly changes in the ECM program?
I don’t notice any difference in 0-100 WOT really but I haven’t tried towing yet
