Hey Ecoboosters,
I've read the forum for awhile but finally got around to posting. I bought a 2015 nonPP SHO over the summer and have done a few things- Livernois Tune, 3bar map, gapped plugs, intake, thermostat. Basically the Livernois T440 kit. I just slapped on my winter wheels and tires last night and it's looking pretty sad. Oh well, makes the summer wheels so much better. I'm in MN so if anyone here is around the twin cities hit me up.
Ben
