DiabloSport makes the best tuners for our cars. WhiteOut529 isn't quite correct in saying it's not available for our cars - tuning IS available but you have to swap out the PCM with a 2010 one (and make some major harness modifications). It's about $3000 from what I've read, and generally not something that we can DIY easily.
AMP is also working on making this process available without the harness modification, though I'm not sure of their progress.
