What's interesting is that the OP to this thread has apparently been contacted by RAM on this issue affecting his RHO, but he didn't want to say anything further out of fear that that might jeopardize his resolution, which infers that RAM is aware of this board.
I have an RHO on order as well, just waiting to be shipped to the dealer, and I'm on the fence about taking delivery, given RAM's handling of this issue. All you have to do is just tell us it was a mistake and you're working to resolve the issue. Not the "here's $3,500 to shut up and go away, and just live with it."
RAM 's not very quick on their feet. Most certainly, RAM can reprogram its PCM tune. They should have nipped this issue in the bud back in March when the OP first took his truck to his dealer and he mistakenly received the EXPORT tune flash, which limited his top speed to 98mph.
I can only specualte/hope that the MY26 RHO's are not being produced at SHAP with a limiter at 98mph, despite being equipped with T rated tires here in the US good for 118mph, but I would like RAM to put on thier big boy and girl pants, own this mistake, and all they have to do is just say, they are working on it.
