Took the H3 to PCM Tune of NC today. My main goal was to disable my flakey Passlock. Kelly and the crew did an awesome job reprogramming my pcm. Changed out spark plugs to ac delco iridium. Original ones were shot. They cannot turn off tpms :no:
On the drive home....wowsers...... where did all that power come from? Feels like a V8 under there now. Accelerates like crazy, kicks down gears easy and smooth.....Amazing!
:horns:
If I can keep off the gas i should get better mpgs. Tech who tuned it said that the air intake won't give much boost so I may leave resonator on there till spring. He said best HP gain is the electric fan kit.
I highly reccomend having your Vortec 3500 or 3700 tuned by PCMforLess. :cheers:
