Whats this about modified trans needing modified tunes?
I'm quite positive that I asked prior to the install of my John Wood transmission whether or not my chip needed to be reburned, and I was told no. I would say that a JW trans is a modified trans, wouldn't you? And now the sales website and other threads here say that a modified trans requires modified tunes. So what gives?
In honesty, my truck runs fine with the combo, BUT I now feel like my tunes are the limiting factor as opposed to the transmission. I was planning to send the chip in for some changes to the tunes when I get home from this deployment, but now I'm wondering if I'll have to pay the $200 upcharge to get what I'm after due to this change in procedure.
