Yes, this thread has been dead for awhile so I thought i should kick it in the pants. Snipe, do you happen to know the long term plan for the state of Texas with regard to no emissions testing for diesel vehicles? I ask this as if we both were to have the software mod and bypass our DPF, we would be at the mercy of the state not changing their mind on testing. I've got a while beofre warranty is up (25 months or 27,000 miles to go). Likely i will reach time first.
