Anyone have any issues with the 8 speeds not liking an engine tune? Iv'e done 2 (both are 8hp70's), 1 challenger 1st with no issues whatsoever & the second in a crew cab truck that I did was fine for a day and a half & then developed a slipping issue so says the customer. The only thing I change with tq management is brake torque management & I haven't ridden in the truck. The customer works at a dodge dealership and after the issue occurred, he took it upon himself to overwrite the pcm with factory updates & the problem went away. We reflashed the .hpt tune and issues came back, customer is convinced the tune fried his trans, this is a first for me. If anyone has any useful input I'd love to hear it.
