    Need to wake up my wife's Suburban

    The ole girl just turned 100k on the clock, always dealer serviced. Its a 2007 with the LC9 5.3. Keeps popping a P0335 even though I changed the wiring and the sensor and the dealer did as well. Once we find someone who will actually fix it instead of giving it back to us saying they could not duplicate the gripe, I want to do a few tasteful mods. One is I would like to have it tuned with EFI Live, I can't stand the stock TCM tuning. Truck has always felt like a dog. I want better driveability and better throttle response. Don't care about the AFM. Thinking about a cam that will help with this as well as giving a bit more power. Nice streetable power. Power in the lower rpms. Looking forward to some ideas. I am currently deployed right now otherwise I would call.
