Sub'd - looking for similar. I wanted so badly to get an Idaho Rob tune for my 06 LBZ, but didn't have the funds at the time etc. Finally got the money prioritized and the EPA ban shut them down (from tuning). So now I'm not sure what to do. I don't want enough power to destroy anything, don't want to upgrade my trans, just keep reading about people saying "how it feels like a brand new truck, runs cleaner, etc." with a good low key set of tunes.
But at the same time, I'm now wondering if I shouldn't just keep it stock, as I don't want to have to buy a new truck for many more years since I daily drive a commuter car now vs. my truck, and just use it to tow our 5th wheel, and weekends to keep it moving. Has 110,000 or so miles on it.
